The total cost of repair if the mechanic takes 2 hours to make a repair is $105
Given the cost of a repair of a mechanic expressed according to the function rule C(h) = 35h +35
where;
h is the number of hours it takes to complete the repair
If the mechanic takes 2 hours to make a repair, this means that h = 2
Substitute h = 2 into the function to get the cost of repair
C(2) = 35(2) + 35
C(2) = 70 + 35
C(2) = 105
Hence the total cost of repair if the mechanic takes 2 hours to make a repair is $105
