➷ Simply substitute the values into the equations to see if it's correct:
Since the time taken will be more than 2 hours, we can try it with the value 3
t(x) = 70 + 5(3) = 85
g(x) = 30 + 15(3) = 75
As you can see, this is the incorrect choice as when a value more than 2 hours is used, the second engineer has a cheaper cost.
