Gabriela buys a basketball for $78 and a soccer ball for $32 she must pay 8.5% sales tax. what is the total amount she must pay?

Hello!

Add the costs of the basketball and the soccerball together:

78 + 32 = 110

Next, Gabriella must pay 8.5% sales tax. Sales tax is money collected by the government, so it is added onto the purchase.

First, we must find what 8.5% of 110 is. To do that, convert the percentage to a decimal by dividing it by 100, then multiply the total cost of the two balls by the decimal.

8.5% ÷ 100 = 0.085

110 × 0.085 = 9.35

Finally, add the sales tax to the cost of the two balls:

110 + 9.35 = 119.35

ANSWER:

The total amount Gabriella will pay is $119.35.
