Question

Jason has a coupon for $2.50 off any electronic book for an online book store. If the original price, in dollars, of an electronic book is p and the discounted price, in dollars, is d, which table shows the relationship between p and d?

Answer 1

Given:

$2.50 off any electronic book for an online bookstore.

     d = discounted price in dollars

p = d + $2.50
