Question

Paula spent 30% of the money she earned from mowing lawns last summer. If Paula spent $45, what is the total amount of money she earned mowing lawns last summer?

Answer 1

$150

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
