Given : Carlos has $50 in his savings account. He deposits $100 on his birthday, and then another $25 every month.

To Find: Which equation can be used to find the number of months it would take him to reach a balance of $500?

Solution:

Carlos has $50 in his savings account.

He deposits $100 on his birthday.

Let m be the number of months

He save $25 every month

So, he saves in x months = 25 m

Now wants to reach a balance of $500.

So, equation becomes:$50+100+25m = 500$

                                    :$150+25m = 500$    

Hence Equation can be used to find the number of months it would take him to reach a balance of $500 is $150+25m = 500$
