Question

Brad puts an equal amount of money in his savings account once a month. He started with $25. The next month, he had $35 in his account. Two months after that, he had $55 in his account. How much money will Brad have in his account after 6 months?

Answer 1

He adds $10 a month. He starts with $25. $10 times 6 months equals $60. $25+$60=$85

Answer 2

First, find how much money he puts into his account each month.

Month 1 - starting amount = 35 - 25 = 10.

Using this information, you can write the equation:
t = total amount  m = number of months after start
t = 25 + 10m

You can check whether or not this equation is correct by plugging in the other information given.
55 = 25 + 10(3)
55 = 25 + 30
55 = 55
The equation is correct.

Now, you can plug in 6 for the number of months.
t = 25 + 10m
t = 25 + 10(6)
t = 25 + 60
t = 85

Brad will have $85 in his account after six months.
