Answer:

Kindly check explanation

Explanation:

Given the expression :

Total cost after tax = 0.08(50h) + 50h

a. What part of the expression represents the amount of tax Deborah has to pay? Explain

0.08(50h) represents Tha amount of tax Deborah has to pay. This can be interpreted as :

Recall;

Tax amount = tax rate * cost

Cost of repair = 50h = 50 per hour

Tax rate = 0.08 = 8% of the total cost;

Hence; 0.08(50h) = tax Deborah has to pay.

What would the expression be if the company charged Deborah $45 per hour to repair the computer (plus tax)?

If she was charged $45 per hour plus tax. Expression becomes ;

Total cost after tax = 0.08(45h) + 45h

= 3.6h + 45h

= 48.6h
