Question

The original price of a computer is $599.99. Suzie has a 15%-off coupon for the computer. A sales tax of 7% will be added to the sale price of the computer. Which expression would calculate how much Suzie will pay for the computer?

A.
$599.99(0.85)(0.07)

B.
$599.99(0.85)(1.07)

C.
$599.99(0.15)(1.07)

D.
$599.99(0.15)(0.07)

Answer 1

B

Explanation:

It can't be A or D as in those the value supposedly representing the sales tax (.07) would further lower the price.

It can't be C as multiplying the 599.99 by .15 would solve for 15% of 599.99, not 15% off.

Therefore we are left with B
