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

A

(i may be wrong)

Answer 2

A. 5c + 1.25 = 8.75

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
