Keith plans to buy a car in the future.He currently has $3000 saved up to buy a car. How much money does he need to save per month over the next 24 months in order to have some extra money left after buying 20000 dollar car.

about $709 per month

Step-by-step explanation:

Okay, so in order to solve this question, we should follow this formula:

3,000 + 24x 20,000

where 24 is the amount of time we have and x is the variable we are using as to show the unknown amount of money earned per month.

3,000 + 24x 20,000

-3,000               -3,000

24x 17,000

/24           /24

x approximately 709 dollars

so, we substitute x for 709

3,000 + 24(709) 20,000

3,000 + 17,016 20,000

20,016 20,000

which is true

Hope this helps :)
