on thursday, the local big box store gives a 15% discount on purchases. the items in tiffany’s cart total $96.82. she needs to know the cost of the items with the discount. so, she multiplies 15% times $96.82 and subtracts the amount from $96.82. which expression would give tiffany the same result in one step?

a.0.15(96.82)
b.0.85(96.82)
c.1.15(96.82)
d.96.82 – 0.15(96.82)

B. 0.85(96.82)

Step-by-step explanation:

Let the total cost of items purchased before discount = 1  

Discount on purchases = 15 % = 0.15

Cost of items purchased after discount = (1 - discount) × cost of items in tiffany's cart

Cost of items purchased after discount = (1 - 0.15) of 96.82

Cost of item purchased after discount = 0.85 (96.82)

Therefore option B is the correct answer.
