Question

A swimming pool had a list price of $575.25 and was on sale for 10% off. Sara had a coupon for an extra $75 off. What will her cost be before tax?

Answer 1

First find the reduce price (based on the 10% sale - i.e this means if the cost is reduced to 90% of its original non-sale price)

Then subtract another $75 due to the coupon to obtain the end cost:

$575.25*(1-0.10) - $75 = $442.73

Answer is: $442.73
