Question

Brian buys 5 cookies and 1 bottle of water. The total cost is $8.75. If the bottle of water costs $1.25, which equation can be used to determine the cost of 1 cookie?
A, 5c+1.25=8.75
B, 5(1.25)+c
C, 5c+8.75=1.25
D, c+1.25=8.75

Answer 1

Answer:

A. 5c + 1.25 = 8.75

Step-by-step explanation:

Where c is cost of one cookie

5c + 1.25 = 8.75

Subtract 1.25 from both sides

5c + 1.25 - 1.25 = 8.75 - 1.25

5c = 7.5

Divide both sides by 5

c = 7.5/5

c = 1.5

= $1.5

One cookie cost $1.5
