Answer 1

Chad wants to buy some books over the Internet. Each book costs $10.01 and has a shipping cost of $9.96 per order. If Chad wants to spend no more than $50 for his books, which inequality shows the maximum number of books, p, that he can buy?

9.96p − 10.01p ≤ 50, so p ≤ 1

9.96p + 10.01p ≤ 50, so p ≤ 2

9.96 − 10.01p ≤ 50, so p ≤ 3

9.96 + 10.01p ≤ 50, so p ≤ 4

i got b but it was wrong can you be please walk through on what i did wrong and help me find the answer

Answer 2

There are two costs you need to account for. The cost of the book, which changes depending on how many books you buy, and the shipping cost, which stays the same no matter how many books are bought. The cost of the books is equal to the cost per book ($10.01) times the number of books bought. The shipping cost is always $9.96

So your equation for the total cost is going to be 10.01p + 9.96

And you just solve for p

Answer 3

can you help me walk through the problems i have 9 more questions i just need help to know what i did wrong and how to get the right answer please ill do anything i need help please @LastTrainHome22

Answer 5

Sorry, I had to run to class. Still need help?

Answer 6

yes but with a different question @LastTrainHome22

Answer 7

Kim surveyed 80 students at her school and found that 0.65 of the students she surveyed said their favorite class is math. Another 15% of the students she surveyed reported that their favorite class is science. How many more students in the survey prefer math over science?

12

15

28

40
i got A the first time but its wrong can you tell me what i did wrong and how i can get the right answer

Answer 8

The answer is D. I think your error was misreading the problem. 65% of students chose math and 15% chose science. I believe you calculated it as 65% math and 80% science

Answer 9

thanks can you help me with a few more

Answer 10

sure

Answer 11

oh how did you get the answer to the last question
@LastTrainHome22

Answer 12

Since 65% chose math you take 80*0.65 to get 52 students
15% chose science, so 80*0.15 for 12 students

52-12 is 40 students more for math

Answer 13

ohh ok i get tht ok hold on a sec

Answer 14

ok im back here is another question i got wrong
Michelle did a survey in four butterfly parks and wrote the following observations:


Butterfly Park Survey
Park Number of Red Butterflies Total Number of Butterflies
A 33 60
B 36 78
C 40 89
D 24 59


Based on the survey, which park had the greatest percentage of red butterflies?
Park A

Park B

Park C

Park D
i got c can you explain how i got it wrong and how you got the correct answer

Answer 15

The percentage is the number of favorable divided by the number seen.
For this the best way to solve it is to calculate the percentage for each part.

A: 33/60 = 0.55
B:36/78 = 0.462
C: 40/89 = 0.449
D: 24/59 = 0.407

So A has the largest percentage

Answer 16

what do think i got wrong on the question
im sorry i keep asking you thth but i guessed on the assignment and my teacher said i need to explain it

Answer 17

I cant be sure without seeing your work. I just happened to make the same mistake as you on the first problem :P

Answer 18

Naomi works in a music shop and earns $42 per day. She earns an extra $2 for each CD she sells. If Naomi wants to earn at least $80 per day, which inequality shows the minimum number of CDs, n, that she should sell?

42 + 2n ≤ 80, so n ≤ 19

42 + 2n ≥ 80, so n ≥ 19

42 + 2n ≥ 80, so n ≥ 36

42 + 2n ≤ 80, so n ≤ 36

Answer 19

Part 1 is writing an expression for how much money is being made. This is the left side of the equation, and since theyre all the same I'm assuming you understand that part. Step two is setting the inequality. SInce you want to make MORE than $80 per day, you set the inequality so that the expression for how much money you make is greater than the goal of 80. Step 3 is solving for n using your algebra.

Answer 20

do you know where i went wrong

Answer 21

Again, not without seeing your work.

Answer 22

Most likely you either put the inequality the wrong way, or made a calculator error

Answer 23

A theater company charges $7.50 per ticket for people of all age groups. If c represents the total number of children who bought tickets and a represents the total number of adults who bought tickets, which expression best represents the total money earned by the company from the sale of tickets?

7.5c + a

c + 7.5a

15(c + a)

7.5(c + a)
@LastTrainHome22

Answer 24

How would you calculate the amount of money from each age group?

Answer 25

with 7.50

Answer 26

okay, so 7.50*c + 7.50*a right?

Answer 27

Then you can factor out the 7.50 using the distributive property

Answer 28

so how do i use it

Answer 29

distributive property says A*(B+C) =AB+AC

Answer 30

oh o

Answer 32

@LastTrainHome22 i promise this and one more is it please

Answer 33

hmm?

Answer 34

can you help me with this one and one more i promise

Answer 35

what is the question?

Answer 36

A theater company charges $7.50 per ticket for people of all age groups. If c represents the total number of children who bought tickets and a represents the total number of adults who bought tickets, which expression best represents the total money earned by the company from the sale of tickets?

7.5c + a

c + 7.5a

15(c + a)

7.5(c + a)
@LastTrainHome22

Answer 37

This is the one we talked about earlier? you get 7.5c + 7.5a , and then factor out the 7.5?

Answer 38

so thts the answer
@LastTrainHome22

Answer 39

7.5(a+c)

Answer 40

last one

Answer 41

The sum of two numbers is 77. The greater number is 5 more than the smaller number. Which equation can be used to solve for the smaller number?

x(x − 5) = 77

x(x + 5) = 77

x − (x + 5) = 77

x + (x + 5) = 77

Answer 42

Okay, so it says the SUM of two numbers, so we know we will be adding two numbers together. We know that the second number is equal to the first number + 5, and we know that the two numbers together equal 77

Answer 43

what do i do now

Answer 44

Write down the thought in terms of numbers. let x represent the first number. this means the second number is x+5. To get the sum you add the first number to the second, so x+x+5

Answer 45

thats it ?

Answer 46

yep

Answer 47

thanks is there something i could do for you to repay cus i feel bad

Answer 48

Nah, its fine. Good luck with the rest of your stuff

Answer 49

thanks
