13 weeks

You save money in a shoebox under your bed. At first, you had $16.25 in the box. Each week you put your $3 in the shoebox. You spend $4.25 on ice cream each week. In how many weeks will your money run out?

To find out in how many weeks your money will run out, we need to track the amount of money you have in the shoebox each week until it reaches zero.

Let's break down the information given:
1. Initial amount of money in the shoebox: $16.25
2. Weekly amount added to the shoebox: $3
3. Weekly amount spent on ice cream: $4.25

To find out how many weeks it will take for your money to run out, we can use the following steps:

1. Subtract the weekly expense from the weekly savings to determine the change in the money in the shoebox each week:

Weekly change = Weekly savings - Weekly expense
Weekly change = $3 - $4.25
Weekly change = -$1.25

2. Calculate the number of weeks it will take for the money in the shoebox to reach zero by dividing the initial amount by the weekly change:

Number of weeks = Initial amount / Weekly change
Number of weeks = $16.25 / -$1.25

To handle the negative value in this case, we can consider it as the absolute value indicating a decrease:

Number of weeks ≈ $16.25 / $1.25

3. Performing the division:

Number of weeks ≈ 13

Therefore, it will take approximately 13 weeks for your money to run out.
