Calculating Total Donations from Donors

The video tutorial explains how Delan raises money through a fundraiser by walking laps. It introduces formulas for calculating contributions from two donors, A and B, based on the number of laps walked. The tutorial then demonstrates how to combine these formulas to find the total amount of money raised. Finally, it confirms the correct formula for total earnings by adding the contributions from both donors.

What is the formula used to calculate the money raised from Donor A?

• a of w = 25t - 15

• a of w = 15t + 25

• a of w = 25t + 15

• a of w = 15t - 25

How is the money raised from Donor B calculated?

• B of w = 5t - 0.5

• B of w = 0.5t + 5

• B of w = 5t + 0.5

• B of w = 0.5t - 5

What does the variable 'W' represent in the formulas?

• The time taken to walk

• The total money raised

• The number of laps walked

• The number of donors

Which operation is used to find the total money raised from both donors?

• Subtraction

• Division

• Addition

• Multiplication

What is the formula for the total amount of money raised from both donors?

• C of w = a of w - b of w

• C of w = a of w / b of w

• C of w = a of w + b of w

• C of w = a of w * b of w

Why is addition used to find the total money raised?

• Because it divides the amounts

• Because it multiplies the amounts

• Because it subtracts the smaller amount

• Because it combines the amounts from both donors

Which answer choice correctly represents the total money formula?

• C of w = a of w + b of w

• C of w = a of w - b of w

• C of w = a of w * b of w

• C of w = a of w / b of w
