Raphel wants a new care, he needa a down payment of $3,000.If he saves $340 each month, about how many months will it take him t
Andre45 [30]
Hello! I would love to help!

Okay, we know that Raphel has to pay 3,000 dollars in a certain amount of months. Let's let "m" represent the amount of months it will take him.

Now, if we know that he saves 340 dollars a month, we can multiply the unknown amount of months, "m" by 340 to find how many will get 3000.

Here's our equation:

340m = 3000

Alright let's solve for m.

Divide both sides by 340.

340m/340= m

3000/340=8.824

So know we know m= 8.824, or exactly 8.824 months to save 3000 dollars.

However, it is really hard to count 8.824 parts of a month. Let's round it to the nearest whole, nine.


So, that means your answer is 9 months!

Hope this helped! Comment if you have questions!
