Answer 1

9 months until Lanie has saved $2,176.

Explanation:

Given:

Lanie is saving money to buy a car. She saved $772 so far.

She earns $157 every month.

Now, to find the months until Lanie has saved until $2,176.

Let the number of months Lanie has saved be
`x.`

She earns per month = $157.

She saved so far = $772.

According to question:

So, to get the months lanie has saved until $2,176 we write an equation.

`157x+772=2176`

Subtracting both sides by 772 we get:

`157x=1404`

Dividing both sides by 157 we get:

`x=8.95`

So, the number of months nearest to the month = 9.

Therefore, 9 months until Lanie has saved $2,176.
