Introduction
In the world of mathematics, problems often arise from real-life scenarios. One such scenario is the case of Mario, who spent a total of $87.33 last week but failed to keep a record of his expenses. Fortunately, Mario has all but one of his receipts, which he has entered into his expense spreadsheet. In this article, we will delve into the world of mathematics to uncover the mystery of Mario's expenses and find the missing receipt.
The Data
Mario's expense spreadsheet contains the following information:
| Date | Description | Amount |
|---|---|---|
| 2023-02-20 | Coffee | $2.50 |
| 2023-02-21 | Lunch | $8.00 |
| 2023-02-22 | Gas | $20.00 |
| 2023-02-23 | Dinner | $15.00 |
| 2023-02-24 | Movie | $12.00 |
| 2023-02-25 | Snacks | $5.00 |
| 2023-02-26 | Groceries | $30.00 |
| 2023-02-27 | Unknown | $5.33 |
The Problem
The problem is to find the missing receipt, which is the unknown expense on February 27th. To do this, we need to analyze the data and find a pattern or relationship between the different expenses.
Analyzing the Data
Let's start by analyzing the data. We can see that the total amount spent by Mario is $87.33. We can also see that the unknown expense on February 27th is $5.33.
| Date | Description | Amount |
|---|---|---|
| 2023-02-20 | Coffee | $2.50 |
| 2023-02-21 | Lunch | $8.00 |
| 2023-02-22 | Gas | $20.00 |
| 2023-02-23 | Dinner | $15.00 |
| 2023-02-24 | Movie | $12.00 |
| 2023-02-25 | Snacks | $5.00 |
| 2023-02-26 | Groceries | $30.00 |
| 2023-02-27 | Unknown | $5.33 |
Finding the Pattern
To find the pattern, let's calculate the total amount spent by Mario for each day:
| Date | Total Amount |
|---|---|
| 2023-02-20 | $2.50 |
| 2023-02-21 | $2.50 + $8.00 = $10.50 |
| 2023-02-22 | $10.50 + $20.00 = $30.50 |
| 2023-02-23 | $30.50 + $15.00 = $45.50 |
| 2023-02-24 | $45.50 + $12.00 = $57.50 |
| 2023-02-25 | $57.50 + $5.00 = $62.50 |
| 2023-02-26 | $62.50 + $30.00 = $92.50 |
| 2023-02-27 | $92.50 + $5.33 = $97.83 |
The Missing Receipt
We can see that the total amount spent by Mario on February 27th is $97.83, which is $10.50 more than the total amount spent by Mario on February 26th. This suggests that the missing receipt is for an expense of $10.50.
Conclusion
In conclusion, we have analyzed the data and found the missing receipt. The missing receipt is for an expense of $10.50, which is the difference between the total amount spent by Mario on February 27th and the total amount spent by Mario on February 26th.
