Answer 1

Answer:

A discount of 15% off the regular price

Step-by-step 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
