Harriet wants to buy items worth $248.50. She is using a store coupon for 25 percent off her purchases. She has to pay 5 percent sales tax. Calculate the total cost of the items. A.
$195.70
B.
$186.38
C.
$177.06

Starting price is : $248.50
Price with 25% off :
$248.50 x ( 1 - 0.25 ) = $248.50 x 0.75 = $186.375
After that she has to pay 5 % sales tax:
$186.375 x 1.05 = $195.70

The total cost of the items is $195.70. So A is your final answer.
