Question

You have a piggy bank with $4 in it. Every month you get an allowance and add $5 to the piggy bank. Which of the following equations represent the amount of money in the bank after "x" months?

Answer 1

Amount of money in bank after “x” months = 4 + 5x

X represent how many months you keep adding $5 to your bank.

Check:

4+5(1) = 9 dollars first month
4+5(2)= 14 dollars second month
4+5(3)= 19 dollars third month
And so on...

Hope that helps!
