Answer:
24 pounds
Explanation:
Let's call the weight of the empty wheelbarrow X, and the weight of dirt to fill the wheelbarrow Y.
So, we can formulate the following equations:
X + Y = 60
X + (1/4)*Y = 33
Subtracting the second equation from the first one, we have:
3/4 * Y = 27
Y = 27 * 4 / 3 = 36
Now, we can calculate X:
X + 36 = 60
X = 24 pounds
