Answer:

The maximum number of pounds p is 224
Step-by-step explanation:
Let
p ----> the maximum number of pounds he can pull without going over the weight limit
we know that
121 pound of rock in the wheelbarrow plus p pounds must be at most 345 pounds
In this problem the word "at most" means "less than or equal to"
so
The inequality that represent this situation is

solve for p
subtract 121 both sides


therefore
The maximum number of pounds is 224
Least 8.334
67/8
8.38
Greatest 8 4/9
