This is a multi step problem. For this we do system of equations.
2.5x + 7y = 82.50
X+y = 24
To do the elimination method we have to make the y values equals to each other so we multiply the x+y=24 equation by 7
7x +7y = 168
-
2.5x + 7y = 82.50
———————————-
4.5x = 85.50
————————-
4.5. 4.5
X = 19

Kindly check explanation
Step-by-step 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
