Trina is purchasing a new bike. the store is having a 20% off sale, and she has a 10% coupon. the original price of the bike is $89.75. what is the final price?

We know the original price of the bike:

price_original=$89.75

In order to calculate the final price, we should calculate the following: original price-sale-coupon

The sale is 20%, which means: sale=20/100*$89.75=0.2*$89.75=17.95

The coupon is 10%, which means: coupon=10/100*$89.75=0.1*$89.75=8.975

The final price is: price_final=$89.75-17.95-8.975=$62.825
