To solve this problem, we have to estimate how much additional weight can be added to the crate (w).
If the crate can hold 1700 pounds, we must subtract the weight that we have already added (110 pounds), in order to find out how much additional weight the box can hold.
Because this is an estimate, I am going to round 110 pounds to 100 pounds to make our calculations simpler.
1700 pounds - 110 pounds = w
1700 pounds - 100 pounds ≈ w
w ≈ 1600 pounds
Therefore, your answer is C. 1,600 pounds
Hope this helps!
