Required
The best deal
See attachment for complete question.
For (a):
[tex]Discount = 5\%[/tex]
[tex]Coupon = \$10[/tex]
First, apply discount.
[tex]New\ price = Regular * (100\% - Discount)[/tex]
[tex]New\ price = Regular * (100\% - 5\%)[/tex]
[tex]New\ price = Regular * 95\%[/tex]
[tex]New\ price = \$285 * 95\%[/tex]
[tex]New\ price = \$270.75[/tex]
Remove coupon of $10
[tex]New\ price = \$270.75 -\$10[/tex]
[tex]New\ price = \$260.75[/tex]
For (b):
[tex]Discount = 15\%[/tex]
Apply discount
[tex]New\ price = Regular * (100\% - Discount)[/tex]
[tex]New\ price = Regular * (100\% - 15\%)[/tex]
[tex]New\ price = Regular * 85\%[/tex]
[tex]New\ price = \$285 * 85\%[/tex]
[tex]New\ price = \$242.25[/tex]
For (c):
[tex]New\ price = \$245[/tex]
For (d):
[tex]Coupon = \$10[/tex]
[tex]Rebate = \$15[/tex]
The new price is calculated as:
[tex]New\ price = Regular - Coupon -Rebate[/tex]
[tex]New\ price = \$285 - \$10 - \$15[/tex]
[tex]New\ price = \$260[/tex]
From the list of options, (b) is the best deal because it is the cheapest
