Select the correct answer.
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.
$195.70
$186.38
$177.06
25% as a decimal is 0.25, and since we subtract 25% we use (1 - 0.25)=0.75. The price of the items after discount is $248.50*0.75 = $186.38 The sales tax (5% = 0.05) is added on, so we multiply by (1 + 0.05) = 1.05 $186.375*1.05 = $195.699 = $195.70
