Calculating Total Expenses: A Math Problem

In this article, we will delve into a real-world math problem that involves calculating total expenses. Michelle buys $2 \frac{1}{2}$ yards of fabric and 3 rolls of ribbon. The fabric costs $\$7.00$ per yard, and each roll of ribbon costs $\$2.50$ . We will use mathematical concepts to determine how much money Michelle spends.

Understanding the Problem

To solve this problem, we need to understand the given information and the mathematical operations involved. Michelle buys two and a half yards of fabric and three rolls of ribbon. The cost of fabric is $\$7.00$ per yard, and the cost of each roll of ribbon is $\$2.50$ . We need to calculate the total cost of fabric and the total cost of ribbon, and then add these two amounts to find the total expenses.

Calculating the Cost of Fabric

The cost of fabric is calculated by multiplying the number of yards of fabric by the cost per yard. Since Michelle buys $2 \frac{1}{2}$ yards of fabric, we need to convert this mixed number to an improper fraction or a decimal. Let's convert $2 \frac{1}{2}$ to a decimal.

$2 \frac{1}{2} = 2 + \frac{1}{2} = 2 + 0.5 = 2.5$

Now that we have the decimal equivalent of $2 \frac{1}{2}$ , we can calculate the cost of fabric.

Cost of fabric = Number of yards of fabric x Cost per yard = 2.5 x $\$7.00$ = $\$17.50$

Calculating the Cost of Ribbon

The cost of ribbon is calculated by multiplying the number of rolls of ribbon by the cost per roll. Since Michelle buys three rolls of ribbon, we can calculate the cost of ribbon as follows:

Cost of ribbon = Number of rolls of ribbon x Cost per roll = 3 x $\$2.50$ = $\$7.50$

Calculating Total Expenses

Now that we have calculated the cost of fabric and the cost of ribbon, we can add these two amounts to find the total expenses.

Total expenses = Cost of fabric + Cost of ribbon = $\$17.50$ + $\$7.50$ = $\$25.00$

Therefore, Michelle spends $\$25.00$ in total.

Conclusion

In this article, we used mathematical concepts to calculate the total expenses of Michelle. We converted a mixed number to a decimal, calculated the cost of fabric and ribbon, and added these two amounts to find the total expenses. This problem demonstrates the importance of mathematical operations in real-world scenarios.
