Answer:

12.5 hrs

Step-by-step explanation:

For auto body charges, the equation will be

cost = 125 + 18 h..............eq 1

For car care charges, the equation will be

cost = 200 +12 h.............eq 2

for the cost to be equal,

From eq 1 and eq 2

125 + 18 h = 200 + 12h

18h - 12h = 200-125

6h = 75

h = 75/6 = 12.5 hrs

12.5 hrs both shops need to work for the prices to be equal
