Question

Levi paints faces at an annual carnival. His goal this year is to earn $100. He spends $15 on supplies and will work for 2.5 hours. How much will he need to earn in dollars per hour in order to reach his goal

Answer 1

He needs to earn $46 per hour in order to reach his goal

Explanation:

Here, we are interested in knowing how much in dollars per hour is needed to be earned in order to reach the goal of $100

Let the amount to be earned be $x per hour

So the total amount earned in 2.5 hours will be 2.5 * $x = $2.5x

Now, this amount, minus the amount on supplies = the amount to be earned

Hence;

Mathematically;

2.5x - 15 = 100

2.5x = 100 + 15

2.5x = 115

x = 115/2.5

x = $46
