Answer:
$150
Step-by-step explanation:
From the question, it is said that Paula spent 30% of the money she earned mowing lawns. This 30% is equal to $45.
Now we need to calculate how much she actually earned. Since we do not know how much she earned, we can represent this amount by $X.
Mathematically we can write the equation as:
30% of $X = $45
This means:
30/100 * X = 45
30x = 4500
X = 4500/30
X = $150
