Introduction

In the world of mathematics, problems can arise from even the most mundane situations. A bowling league's sandwich order is a perfect example of this. With 160 sandwiches to be distributed among its members, the league must ensure that each type of sandwich is allocated fairly. In this article, we will delve into the mathematical world of ratios and proportions to determine the number of turkey and roast beef sandwiches that will be served.

The Problem

The table below shows the number of different types of sandwiches that were ordered:

Type of Sandwich	Number of Sandwiches
Turkey	x
Roast Beef	y
Ham	20
Cheese	30
Veggie	40

The ratio of turkey sandwiches to roast beef sandwiches is 5:3. This means that for every 5 turkey sandwiches, there are 3 roast beef sandwiches. We are given that the total number of sandwiches is 160.

Mathematical Approach

To solve this problem, we will use the concept of ratios and proportions. We know that the ratio of turkey sandwiches to roast beef sandwiches is 5:3. This can be represented as a fraction:

\frac{x}{y} = \frac{5}{3}

We are also given that the total number of sandwiches is 160. This can be represented as an equation:

x + y + 20 + 30 + 40 = 160

Simplifying the equation, we get:

x + y = 70

Now, we can substitute the expression for y from the ratio equation into the simplified equation:

x + \frac{3x}{5} = 70

Multiplying both sides by 5 to eliminate the fraction, we get:

5x + 3x = 350

Combine like terms:

8x = 350

Divide both sides by 8:

x = 43.75

Since we cannot have a fraction of a sandwich, we will round down to the nearest whole number. Therefore, the number of turkey sandwiches is 43.

Finding the Number of Roast Beef Sandwiches

Now that we have found the number of turkey sandwiches, we can find the number of roast beef sandwiches using the ratio equation:

\frac{x}{y} = \frac{5}{3}

Substituting x = 43, we get:

\frac{43}{y} = \frac{5}{3}

Cross-multiplying, we get:

129 = 5y

Dividing both sides by 5, we get:

y = 25.8

Rounding down to the nearest whole number, we get:

y = 25

Conclusion

In this article, we used the concept of ratios and proportions to determine the number of turkey and roast beef sandwiches that will be served at the bowling league's tournament. We found that the number of turkey sandwiches is 43 and the number of roast beef sandwiches is 25. This problem demonstrates the importance of mathematical problem-solving in real-world situations.
