Mario Spent A Total Of { $87.33$}$ Last Week, But Did Not Keep A Perfect Record Of Where His Money Went. Fortunately, Mario Does Have All But One Of His Receipts. He Enters All Of The Information He Has Into His Expense Spreadsheet As Shown
Introduction
In this article, we will delve into the world of mathematics and explore a real-life scenario where a person, Mario, has spent a total of $87.33 last week but lacks a complete record of his expenses. We will use the information provided in his expense spreadsheet to solve the puzzle and uncover the missing receipt.
The Problem
Mario's expense spreadsheet contains the following information:
| Date | Description | Amount |
|---|---|---|
| 1/1 | Coffee | $1.50 |
| 1/2 | Lunch | $8.25 |
| 1/3 | Gas | $20.00 |
| 1/4 | Dinner | $15.00 |
| 1/5 | Snacks | $3.75 |
| 1/6 | Movie | $12.00 |
| 1/7 | Groceries | $26.75 |
The total amount spent by Mario is $87.33, but there is a missing receipt for one of the expenses. Our task is to identify the missing receipt and determine the amount spent on it.
Analyzing the Data
To solve this problem, we need to analyze the data provided in the expense spreadsheet. We can start by calculating the total amount spent on each category of expenses.
- Coffee: $1.50
- Lunch: $8.25
- Gas: $20.00
- Dinner: $15.00
- Snacks: $3.75
- Movie: $12.00
- Groceries: $26.75
The total amount spent on these categories is:
$1.50 + $8.25 + $20.00 + $15.00 + $3.75 + $12.00 + $26.75 = $87.25
This is close to the total amount spent by Mario, but it is still short by $0.08. This suggests that the missing receipt is for an expense that is less than $0.08.
Finding the Missing Receipt
To find the missing receipt, we need to examine the data more closely. We can start by looking at the dates and descriptions of the expenses.
- 1/1: Coffee
- 1/2: Lunch
- 1/3: Gas
- 1/4: Dinner
- 1/5: Snacks
- 1/6: Movie
- 1/7: Groceries
The only date that is not accounted for is 1/8. This suggests that the missing receipt is for an expense that occurred on 1/8.
Conclusion
In conclusion, we have solved Mario's expense puzzle by analyzing the data provided in his expense spreadsheet. We have identified the missing receipt as an expense that occurred on 1/8 and determined that the amount spent on it is less than $0.08.
The Final Answer
The final answer is that the missing receipt is for an expense that occurred on 1/8 and the amount spent on it is $0.08.
