Question

Sally wants to buy a bicycle that costs $285. She checks several stores online to find the best deal

Answer 1

A discount of 15% off the regular price

Explanation:

Given

`Regular = \$285`

Required

The best deal

See attachment for complete question.

For (a):

`Discount = 5\%`

`Coupon = \$10`

First, apply discount.

`New\ price = Regular * (100\% - Discount)`

`New\ price = Regular * (100\% - 5\%)`

`New\ price = Regular * 95\%`

`New\ price = \$285 * 95\%`

`New\ price = \$270.75`

Remove coupon of $10

`New\ price = \$270.75 -\$10`

`New\ price = \$260.75`

For (b):

`Discount = 15\%`

Apply discount

`New\ price = Regular * (100\% - Discount)`

`New\ price = Regular * (100\% - 15\%)`

`New\ price = Regular * 85\%`

`New\ price = \$285 * 85\%`

`New\ price = \$242.25`

For (c):

`New\ price = \$245`

For (d):

`Coupon = \$10`

`Rebate = \$15`

The new price is calculated as:

`New\ price = Regular - Coupon -Rebate`

`New\ price = \$285 - \$10 - \$15`

`New\ price = \$260`

From the list of options, (b) is the best deal because it is the cheapest
