Calculating Donations from Donors

The video tutorial explains how Jeremy raises money through a walkathon fundraiser with contributions from two donors. Donor A's contribution is calculated using the formula A(W) = W + 12, and Donor B's contribution is calculated using B(W) = 0.75W + 10. The tutorial then demonstrates how to derive the total amount of money Jeremy earns from both donors as a function of the number of laps walked, resulting in the formula C(W) = 1.75W + 22.

What is the formula used to calculate the donation from Donor A?

• A of W = W - 12

• A of W = W + 12

• A of W = 12W + 1

• A of W = 12 - W

In the formula for Donor B, what does the term '0.75W' represent?

• The donation per lap walked

• A fixed donation amount

• The total number of laps

• A bonus donation

How do you find the total amount of money Jeremy earns from both donors?

• Multiply the donations from both donors

• Subtract the donation from Donor B from Donor A

• Add the donations from both donors

• Divide the donation from Donor A by Donor B

What is the first step in calculating the total donation using the given formulas?

• Multiply the terms with W from each formula

• Add the terms with W from each formula

• Add the constants from each formula

• Subtract the constants from each formula

What is the combined coefficient of W in the final formula for total donations?

• 1.75

• 2.75

• 1.25

• 0.75

What is the constant term in the final formula for total donations?

• 22

• 12

• 10

• 32

Which of the following represents the final formula for the total amount of money earned?

• C of W = 1.75W + 22

• C of W = 1.75W - 22

• C of W = 0.75W + 22

• C of W = 1.25W + 22

What does the variable W represent in the formulas?

• The number of laps walked

• The donation per lap

• The total donation amount

• The number of donors

How much does Donor B contribute as a fixed amount regardless of laps walked?

• 0.75

• 22

• 10

• 12
