We are given that:
i- The store is having 20% off sale
ii- Trina has a 10% coupon

Therefore, Trina will be having a discount = 20 + 10 = 30% of the bike's price
This means that:
Trina will pay 100% - 30% = 70% of the price

We are given that:
The original price of the bike = <span>$89.75
We now know that:
Trina will pay 70% of its price

Therefore:
Final price = 70% * </span>89.75 = 0.7 * <span>89.75
Final price = $62.825

Hope this helps :)</span>

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
