Question

Helen went to the grocery store to buy potatoes. The store charges $1.06 for each pound of potatoes. On the way out of the store, Helen picked up a gallon of ice cream at a cost of $4.32. If Helen spent $12.80 at the store, how many pounds of potatoes did she purchase? Assume tax is included in the given price.

Answer 1

So the total is 12.80 so you know the potatoes plus the ice cream are going to equal that price.
The ice cream is also a constant factor, so you know that won't have any variable.
The amount of potatoes, however, does change so that needs a variable.
1.06x+4.32=12.80

Answer 2

Can you solve it from there? ^^

Answer 3

Not Really

Answer 4

1.06x+4.32=12.80
You need to isolate the x, so first subtract 4.32 from both sides and tell me what you get

Answer 5

A.9
B. 7
C. 8
D.14 Here's the answer choices

Answer 6

B
1.06+4.32=5.38
12.80-5.38=7.42
7.42/1.06=7 lbs of potatoes
1.06+4.32+12.80-5.38=12.80

So, Helen left with 7 lbs of potatoes

Answer 7

Yess! Thanksss

Answer 8

It's C

Answer 9

How

Answer 10

1.06+4.32=5.38 says Helen only bought one potato and a thing of ice cream

Answer 11

B is the correct answer, just saying.

Answer 12

If you check your work, 7 potatos would be 7.42 and the icecream is 4.32

Answer 13

No variables are needed for this type of equation.

Answer 14

7.42+4.32 is 11.74

Answer 15

not 12.80

Answer 16

The monthly cost of electricity in Smithville is determined by the function

C(e) = $0.18e + $27.41,

where e is the amount of electricity used in kilowatt-hours (kWh) and C(e) is the total cost. If the Fox family used 853 kWh of electricity last month, how much was their bill?

Answer 17

1.06x+4.32=12.80
1.06x=8.48
x=8

1.06(8)+4.32
8.48+4.32
12.80

The answer is C

Answer 18

$0.18(853)+27.41=$180.95

Answer 19

The problem says e is the amount of electricty used, and the Fox faily used 853 kWH, so plug 853 where ever theres an E
C(e) = $0.18(853) + $27.41

Answer 20

Oooh

Answer 21

A company sells each product they make for $90.00. They pay $2,800.00 in monthly costs, such as rent and bills, as well as $75.00 in manufacturing costs per unit. If the company sold 492 units last month, what was their total profit?

Answer 22

how many products did they make?

Answer 23

You need to subtract the price of bills and manufacturing cost per unit from the amount of money they make per unit
90(492)-(2800+75(492))
44280-(2800+36900)
44280-39700
$4,580.00 profit

Answer 24

A.
$34,100.00
B.
$41,405.00
C.
$4,580.00
D.
$6,056.00

Answer 25

So It's c

Answer 26

Yep ^^

Answer 27

Indicate which property is illustrated in Step 5.

Step 1 10 + 9x - 10 - 6x + 5 = 10 + (9x - 10) - 6x + 5
Step 2 = 10 + (-10 + 9x) - 6x + 5
Step 3 = [10 + (-10)] + (9x - 6x) + 5
Step 4 = 0 + (9x - 6x) + 5
Step 5 = (9x - 6x) + 5
Step 6 = (9 - 6)x + 5
Step 7 = 3x + 5

Answer 28

distributive

additive identity

associative

additive inverse

Answer 29

In step 5 you got rid of the +0 because adding zero to a number will equal that number so its not really needed. Which one of those four properties deals with adding?
