Question

A music store is offering a coupon promotion on its CDs. The regular price for CDs is $14. With the coupon, customers are given $4 off the total purchase. Write an equation that relates the number of CDs "c" and the total cost "t."

a) t = 14c - 4
b) t = 4c - 14
c) t = 14 - 4c
d) t = 4 - 14c

Answer 1

The correct equation that relates the number of CDs to the total cost ('t') with a coupon promotion is t = 14c - 4.

So, the correct answer is C.

Step-by-step explanation:

The student wants to find an equation that relates the number of CDs, denoted as c, to the total cost, denoted as t. Since the regular price for CDs is $14 and the coupon provides a $4 discount on the total purchase, we can write the equation as t = 14c - 4. This is because for each CD bought, the cost is $14, and then $4 is subtracted from the total cost regardless of the number of CDs bought.

So, the correct answer is C.
