Question

Ex. 11 An apple computer has a retail price of $1000. Jim's House of Electronics is having a "20%-off sale",

in which all items are discounted to 20% less than retail. Allan has a coupon for 30% off the sale price of
any apple computer. How much does Allan have to pay for a new computer?

Answer 1

he would have to pay $560 because if you take 20% off of the computer using the equation 1000 - (1000 * 0.20) you get 800. This means that the 30% coupon is applied to $800, so using the same template as the equation above, we can do 800 - (800 * 0.30) to get a final answer of 560.
