Question

Since it's Wednesday, Buy for Less gives a 10% discount for purchases. The items in Rhonda's cart total $85.00. She needs to know the cost of the items with the discount. So, she multiplies 10% times $85.00 and subtracts the amount from $85.00 Which expression would give Rhonda the same result in one step?

Answer 1

10% Discount
$85.00
10% x $85.00 = $8.50
$85.00 - $8.50 = $76.50 (this is what Rhonda did)

90% x $85.00 = $76.50
Because 100%-10% is 90%, she only has to find 90% of the original price.
The best expression would be 90% x $85.00.
