Question

You earn $7 an hour helping your neighbor do landscaping work over the summer. You worked a total of 120 hours for your neighbor this summer, how much money did you earn?

Answer 1

`$840`

Explanation:

Let's first set up an equation and identify the variables.

We are given that `$7` is earned every hour worked. We can represent this mathematically as: `7x`, where `x` represents the number of hours. If we were to say this aloud, we would be saying "seven dollars per hour".

`7x`

To make this an equation that can be solvable, we need to set this term equal to something, and we can use another variable.

`y=7x`

We are told that `120` hours were worked. We can plug this into `x`, since `x` represents hours.

`y=7(120)`

Now we need to simplify. Multiply `7` and `120`.

`y= 840`

We found out that `$840` was earned when `$7` was made every hour, for `120` hours.
