Introduction

Francesca is participating in a fun run to raise money for the West Side Children's Hospital. The run is held at Francesca's high school track, where she will be running laps to raise funds for the hospital. The more laps Francesca runs, the more money she raises for the hospital. This scenario presents an excellent opportunity to apply mathematical concepts to real-world problems. In this article, we will explore the mathematical approach to Francesca's fun run fundraiser and how it can be used to raise money for the West Side Children's Hospital.

Mathematical Modeling of the Fun Run

Let's assume that Francesca runs a certain number of laps around the track, and each lap is worth a certain amount of money. We can model this situation using a linear equation. Let's denote the number of laps Francesca runs as x and the amount of money raised per lap as y. The total amount of money raised can be represented by the equation:

y = mx + b

where m is the slope of the line (representing the amount of money raised per lap) and b is the y-intercept (representing the initial amount of money raised).

Calculating the Amount of Money Raised

To calculate the amount of money raised, we need to know the number of laps Francesca runs and the amount of money raised per lap. Let's assume that Francesca runs 10 laps around the track, and each lap is worth $5. We can plug these values into the equation to get:

y = 5x + b y = 5(10) + b y = 50 + b

Since Francesca starts with no initial amount of money raised (b = 0), the total amount of money raised is:

y = 50

Therefore, Francesca raises $50 for the West Side Children's Hospital by running 10 laps around the track.

Optimizing the Fun Run

To maximize the amount of money raised, Francesca needs to run as many laps as possible around the track. However, she also needs to consider the time it takes to run each lap and the fatigue she experiences. Let's assume that Francesca runs at a constant pace of 1 lap per minute. We can model this situation using a quadratic equation:

t = ax^2 + bx + c

where t is the time taken to run x laps, a is the coefficient of the quadratic term, b is the coefficient of the linear term, and c is the constant term.

Solving the Quadratic Equation

To find the optimal number of laps Francesca should run, we need to solve the quadratic equation. Let's assume that the time taken to run each lap is 1 minute, and the fatigue experienced is proportional to the square of the number of laps run. We can plug these values into the equation to get:

t = ax^2 + bx + c t = (1/2)x^2 + (1/2)x + 0

Solving for x, we get:

x = -b ± √(b^2 - 4ac) / 2a x = -1/2 ± √(1/4 - 0) / 1 x = -1/2 ± √1/4 x = -1/2 ± 1/2

Since x represents the number of laps Francesca runs, it must be a positive value. Therefore, we take the positive root:

x = 1/2

This means that Francesca should run approximately 0.5 laps around the track to maximize the amount of money raised.

Conclusion

Francesca's fun run fundraiser presents an excellent opportunity to apply mathematical concepts to real-world problems. By modeling the situation using linear and quadratic equations, we can calculate the amount of money raised and optimize the fun run to maximize the amount of money raised. By running approximately 0.5 laps around the track, Francesca can raise the maximum amount of money for the West Side Children's Hospital.
