Question

Alia buys a computer. The original price of the

computer is $379.99. She uses a coupon for 15%
off any item. She must pay 6.75% sales tax on the
sale price. How much money will Alia spend on the
computer? (Hint....tax goes on the sales price!)

Answer 1

$344.79

Explanation:

379.99 decrease 15% =

379.99 × (1 - 15%) = 379.99 × (1 - 0.15) = 322.9915

322.9915 increase 6.75% =

322.9915 × (1 + 6.75%) = 322.9915 × (1 + 0.0675) = 344.79342625
