Question

A shop sells small boxes and large boxes for storing CDs. A small box stores x CDs, and a large box stores y CDs. Ethan buys 7 small boxes and 5 large boxes, storing a total of T CDs.

a. T = 7x + 5y
b. T = 7y + 5x
c. T = 12xy
d. T = 7xy + 5

Answer 1

The equation to represent the total number of CDs bought by Ethan is T = 7x + 5y.

Step-by-step explanation:

The correct equation to represent the total number of CDs, T, bought by Ethan is T = 7x + 5y. In this equation, x represents the number of CDs a small box can store and y represents the number of CDs a large box can store. This equation accounts for the number of small boxes and large boxes Ethan bought and calculates the total number of CDs stored.
