Answer:
$45/h
Explanation:
So, we have a total maximum cost for the finished product and we have the raw material costs... but we need to figure out the maximum labor cost (for 2 hours).
We can express this as follows (remember it takes 2 hours of labor):
98.62 + 2x <= 189.27
2x <= 90.65
x <= 45.325
Rounded to the nearest dollar: $45
The maximum cost Ethan can afford in labor is $45/h for the 2 hours machining of the parts.
