Answer:
Paul filled 4 bags on Sunday.
Explanation:
Since each bag that was filled weighed 5 pounds then we can use the following equation to solve for the amount of bags, where (x) is the number of bags filled on Saturday and (y) is the number of bags filled on Sunday.
5x + 5y = 30
Now since we are told that on Saturday Paul filled 2 bags then we would only be left with the variable y (number of bags filled on Sunday). We can solve for y
5(2) + 5y = 30
10 + 5y = 30 ... subtract 10 on both sides
5y = 20 ... divide by 5 on both sides
y = 4
Finally, we can see that Paul filled 4 bags on Sunday.
