Kenji earns $32 in 4 hours. How much does he earn per hour?

Answer 1

First, set up the problem using what you know. Here, 4 is the number of hours worked and $32 is how much Kenji earned. We don't know how much they make per hour, so we substitute that with X. The equation is how much they make per hour multiplied number of hours worked is equal to the amount earned:

X * 4 = $32

Next, rearrange the equation to solve for X (how much they make). Since we are multiplying X by 4 to get 32, when we move 4 to the other side of the equation, the operand becomes the opposite: multiply turns into divde. Our new equation is this:

X = 32 / 4

Now just solve for X by dividing 32 by 4:

X = 8

Our answer is Kenji earns $8 an hour.
