Question

Chang and Carlotta solve this problem in two different ways. You have $50 in your bank account. You make $8 per hour mowing lawns. How many hours must you mow lawns to have a total of $130 in your account?

Answer 1

8 hours

Explanation:

You can solve this problem by inputting the values into an equation. Here is the equation below:

`50 + 8x = 130`

Lets solve for x. First you subtract 50 from 130.

1)
`8x = 130 - 50`

2)
`8x = 80`

Next, you divide 80 by 8 to get x by itself.

1)
`x = (80)/(8)`

2)
`x = 10`

This means that you must mow lawns for 8 more hours to get a total of $130 in your bank account.
