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

she needs to count how much 90% ist so
85.00*90%
or 8500*0.9

Answer 2

`90\% * 85`

Explanation:

According to her

Discount = 10%

Total Cost = $85.00

So, Discount amount =
`10\% * 85`

=
`(10)/(100) * 85`

=
`8.5`

Amount to be paid = $85.00 - $8.50

= $76.50

Another way

Since we are given that 10% is discount

So, she need to pay 90% of amount

So, Amount to be paid =
`90\% * 85` = $76.50

Hence the expression would give Rhonda the same result in one step is
`90\% * 85`
