Question

Juliana has $35.00 to spend at the bookstore, where all students receive a 20% discount. Juliana wants to purchase a box that is $28.00 and has a sales tax of 5% after the discount. Which statement below is accurate? A) Juliana needs $0.28 more to buy the book. B) Juliana needs $7.35 more to buy the book. C) Juliana has enough money to buy the book with $5.60 leftover. D) Juliana has enough money to buy the book with $11.48 leftover.

Answer 1

Answer:

Cost of box = 28

cost after discount = 28 - (20 percent of 28)

= 28 - (28/5)

= 22.4

cost including tax = 22.4 + (5 percent of 22.4)

= 28 + (22.4/20)

= 29.12 dollars

Thus she can buy the box and will have 35 - 29.12 = 5.88 dollars leftover
