Answer:
500 lb
Step-by-step explanation:
You have to make a proportion:

77 lb is part of the whole weight ( which we don't know) so 77 will go on top
The problem tells us that 15.4% of the total weight is pecans so 15.4 will go over 100 (since % are out of 100)

Then you cross multiply giving you: 7700 = 15.4x
then you divide 15.4 to both sides to isolate x which will give you 500
I would say they would need to be replaced at separate times. If the tires diameter is greater then the other can travel double the distance without needing to be changed. Thats what i think
