Step-by-step explanation:
Here, we want to know the number of hours that Mr Smith must study each week
From the question, we are told that he must study a minimum of 60 hours total over the course of the 8 weeks
The number of hours he must study each week will be 60/8 = 7.5 minimum number of hours each week
We know that the load is 8713 lbs.

Answer: the empty truck's weight is 8487 lb.
T: empty truck's weight
W: total weight (loaded truck's weight)
L: Load
The equation is:
T = W - L
