Question

Julia is saving money for the down payment on a car. She plans to save for one year. Her parents have offered to contribute $50 a month to her savings. How much does Julia need to save each month in addition to her parents' contribution if she wants to have a $2700 down payment on a car at the end of the year? Define a variable and write an equation to represent this situation.

Answer 1

`12x+600=2700`

$175

Explanation:

Let x represent money saved by her in one month.

So money saved by her in one year (12 months) would be
`12x`.

We can represent our given information as:

`12x+600=2700\\12x=2700-600\\12x=2100\\x=(2100)/(12)\\x=175`

Therefore, she needs to save $175 per month.
