Prompt

A book-of-the-month club charges

17 f or t h e f i r s t b oo k p u r c ha se dd u r in g t h e m o n t han d ana dd i t i o na l

13 for each book after the first. Which equation describes this situation, where

y

is the total cost, in dollars, for books purchased during a month,

x

is the number of books purchased during the month, and

x > 0

y = x + 17

y = 13 x + 17

y = 13 (x - 1) + 17

y = (x - 1) + 17
