Hi kat:}!

Suppose we give this number of bags a name, or rather a symbol.
Let's call it n. That is the first letter of "number of bags", just to make it easy to remember.

Since 1 bag weighs 20 pounds, that means that n bags must weight n x 20 pounds.
This total weight has to be less than the wheelbarrow's capacity of 300 pounds.
We can write that as:

n x 20 <= 300

Let's write a variant of that that between [ math ] tags so that this site's calculator can solve it:

n * 20 = 300

Do you see what the maximum number of bags is that the wheelbarrow can carry?
