Answer:

(D) (10 × 4) + (5 × 4) and 15 + 15 + 15 + 15

Step-by-step explanation:

Given;

total number of boxes of doughnuts sold, T = 15 boxes

the cost of each box of doughnuts, C = $4

The total cost of the doughnuts sold = 4 x 15 =  $60

The only option that contains pair of expressions that is equal to $60 is option D.

(D) (10 × 4) + (5 × 4) and 15 + 15 + 15 + 15

(10 × 4) + (5 × 4) = 40 + 20 = $60

15 + 15 + 15 + 15 = $60
