Question

In April, you have a balance of $75 in your bank account. Each month you deposit $25. Let January = 1, February = 2, and so on. Write an equation for this situation. Use the equation to find the balance in June.

Answer 1

I think this sentence is poorly written and confuses one.

Let January = 1, February = 2, and so on.

This is the way I see it:

If you start out with $75 and add an additional $25 per month for month 1 you would have

75+25

Month 2: you have

75+25+25

For month 3: you have

75+25+25+25

So the general equation would be

$75+n($25) Where n = number of months since the initial deposit of $75.


So in between April and June, you have 2 months after the initial deposit in April, May and June

So the amount in the account would be

Amount=$75+2($25) Which gives us $125
