Answer 1

Given :

Sierra is getting her car fixed at a mechanics. The total cost after tax is represented by 0.065(30h) + 30h, where h represents the number of hours it takes to repair the car.

To Find :

What part of the expression represents the amount of money she will have to pay in tax.

Solution :

Total cost , T = 30h( 1 + 0.065)

T = 30h + 30h(0.065)

T = (30h) + (30h )× 6.5 %

Here, 30h is the cost of repairing the car.

Other part shows the tax she have to pay which is 6.5% of the total amount.

Hence, this is the required solution.
