Question

Angelica's service club is selling flowers for a fundraiser. Each flower costs them $0.50 to purchase. They set the sale price of each flower at the purchase price plus 40%. Write and solve an equation to determine how many flowers they will need to sell to make a profit of $500. Use complete sentences to explain what each number and variable in your equation represents. Write your solution in the context of the original problem.

Answer 1

$0.50 to purchase
sale price = .50(1.40) = $ 0.70
this means they make $ 0.20 profit per flower
0.20f = 500
f = 500/0.20
f = 2500
Angelica's service club would have to sell 2500 flowers to clear a profit of $500.

Answer 2

Thank you so much. I honestly suck at algebra

Answer 3

any more questions

Answer 4

yes.
Max was solving the equation below and isn’t sure if his answer is correct. Explain to Max how he can check his answer and then help him identify any errors he made. Provide the correct solution in your explanation.

3x+6
8
=
7x−1
6
24
1
(
3x+6
8
) =
24
1
(
7x−1
6
)

3(3x+6) = 4(7x−1)
9x+18 = 28x−1
9x−9x+18 = 28x−9x−1
18 = 19x−1
18+1 = 19x−1+1
19 = 19x
1 = x

Answer 5

can you give me medal

Answer 6

how?

Answer 7

okay

Answer 8

Is the original problem:

(3x + 6) / 8 = (7x - 1) / 6

To check to see if x = 1 is correct, substitute the "1" for the "x" in the original problem and see if it works out:

(3(1) + 6) / 8 = (7(1) - 1) / 6
(3 + 6) / 8 = (7 - 1) / 6
9 / 8 = 6 / 6
9 / 8 = 1
FALSE

So x = 1 is not the solution.

And here is where the problem is:

3(3x+6) = 4(7x−1)
9x+18 = 28x−1 <---

You multiplied 4(7x - 1) to get 28x - 1, where it should have been 28x - 4.

Answer 9

thank yooou. and then this one

Angelo took a group of people to the movies and spent $80 on tickets. Adult tickets cost $10, and child tickets cost $6. The equation to represent his cost is 10A + 6C = $80. If there were 5 children in the group, how many adult tickets did he purchase? Show your work and use a complete sentence to explain your solution in the context of the original problem.

Answer 10

Make sure you post this in math. A lot of people well help you more than we can

Answer 11

@ryanwhite499 thanks sorry

Answer 12

5 adults
10a+6(5)=80
10a+30=80
10a-30+30=80-30
10a=50
10a/10=50/10
a=5
there are six children, 30 must be spent, 50 is left, since each adult costs 10, 5 there are 5 adult tickets

Answer 13

any more and if there is go to the math section

Answer 14

do you know how

Answer 15

yes. just one more, though.

Answer 16

i will help you there

Answer 17

ok

Answer 18

wat is it

Answer 19

A quality control inspector is in charge of inspecting drill bits that are produced on an assembly line. The diameter of a drill bit can be modeled by the equation |x − 0.525| = 0.01. Show your work in solving the equation to determine the minimum and maximum diameters of the drill bits.

Answer 20

515 is the minimum diamter
535 is the maximum

its just addition and subtraction, 525+10, 525-10, please don't forget the decimal points.

Answer 21

where are the decimal points?

Answer 22

| x - 0.525| = 0.01

x - 0.525 = 0.01
x = 0.01 + 0.525
x = 0.535

-| x - 0.525| = 0.01
-x + 0.525 = 0.01
-x = 0.01 - 0.525
-x = 0.515
x = - 0.515

minimum is : -0.515 diameter
maximum is : 0.535 diameter

Answer 23

oh okaaaaay i get it
