Question

You have some money in your savings account. You will add $5 each week to your account. By week 19 you have $115. How much money did you start with in your savings account?

Answer 1

Let's call the amount of money you started with in your savings account "x".

In 19 weeks, you added $5 each week, so you added a total of $5 x 19 = $95.

Adding this amount to the initial amount x, we get:

x + $95 = $115

Subtracting $95 from both sides, we get:

x = $20

Therefore, you started with $20 in your savings account.
