Question

a dishwasher is priced at $475. there are two options offered to reduce the price: either a 15% discount off the price or a rebate of $75. which is the better choice, and what is the extra amount saved?
the 15% discount is better; it saves $60 more.
the 15% discount is better; it saves $3.75 more.
the rebate is better; it saves $3.75 more.
the rebate is better; it saves $60 more.

Explanation:

Step1: Calculate savings from 15% discount

To find 15% of $475, we use the formula: $Savings_{discount} = 0.15\times475$
$0.15\times475 = 71.25$

Step2: Compare savings with rebate

The rebate is $75. Now we compare $71.25 (discount savings) and $75 (rebate savings). The difference is $75 - 71.25 = 3.75$. So the rebate saves $3.75 more.

Answer:

The rebate is better; it saves $3.75 more.
