Introduction
In this article, we will explore the cost of school lunches and calculate the total cost for a corresponding number of lunches bought. We will use a simple mathematical approach to determine the total cost.
The Cost of a School Lunch
The cost of a school lunch is $2.50. This is a fixed price that remains the same regardless of the number of lunches bought.
Calculating the Total Cost
To calculate the total cost, we need to multiply the cost of a single lunch by the number of lunches bought.
| Lunches Bought | Total Cost |
|---|---|
| 1 | $2.50 |
| 2 | $2.50 x 2 = $5.00 |
| 3 | $2.50 x 3 = $7.50 |
| 4 | $2.50 x 4 = $10.00 |
Discussion
Let's take a closer look at the table above. We can see that the total cost increases by $2.50 for each additional lunch bought. This is because we are multiplying the cost of a single lunch by the number of lunches bought.
For example, if we buy 2 lunches, the total cost is $5.00, which is $2.50 more than the cost of a single lunch. Similarly, if we buy 3 lunches, the total cost is $7.50, which is $2.50 more than the cost of 2 lunches.
Mathematical Representation
We can represent the total cost mathematically using the formula:
Total Cost = Cost of a Single Lunch x Number of Lunches Bought
In this case, the cost of a single lunch is $2.50, so the formula becomes:
Total Cost = $2.50 x Number of Lunches Bought
Conclusion
In conclusion, the cost of a school lunch is $2.50, and the total cost for a corresponding number of lunches bought can be calculated by multiplying the cost of a single lunch by the number of lunches bought. We can represent this mathematically using the formula:
Total Cost = $2.50 x Number of Lunches Bought
Example Problems
- If a student buys 5 lunches, what is the total cost?
- If a student buys 10 lunches, what is the total cost?
- If the cost of a single lunch increases to $3.00, what is the total cost for 5 lunches?
Answers
- Total Cost = $2.50 x 5 = $12.50
- Total Cost = $2.50 x 10 = $25.00
- Total Cost = $3.00 x 5 = $15.00
