D. 0.50(0.75x + x)
E. 0.50(1.75x)
F. 0.50(2.25x

Answer 1

First we define the varible to use:
 x = represent the number of cookies
 Cameron:
 The amount of cookies he made was:
 x
 Deyonne:
 We can rewrite the amount in different ways:
 x + 0.25x
 1.25x
 Then, the total revenue is:
 0.50 * (x + (x + 0.25x))
 We rewrite:
 0.50 * (x + 1.25x)
 0.50 * (2.25x)
 Answer:
 The following expressions represent possible revenue from the sales:
 F. 0.50 (2.25x
 C. 0.50 (x + 1.25x)
 A. 0.50 [x + (x + 0.25x)]
