Mowing Lawns (Create a table of values for a real-world situation represented by an equation)

The video tutorial explains how John earns money by mowing lawns, with each lawn earning him $20. It introduces the equation y = 20X to represent his earnings, where X is the number of lawns mowed, and Y is the total money earned. The tutorial covers the concepts of independent and dependent variables, demonstrating how to use the equation to calculate earnings and fill a table of values. The lesson concludes with a summary of how to create a table of values for real-world situations using equations.

What does the variable X represent in the equation y = 20X?

• The amount of money John earns

• The time John spends mowing

• The cost of mowing equipment

• The number of lawns John mows

In the context of the equation y = 20X, which variable is dependent?

• Neither X nor Y

• Both X and Y

• Y, the amount of money

• X, the number of lawns

If John mows 3 lawns, how much money will he earn according to the equation?

• $40

• $60

• $100

• $80

What is the total amount John earns if he mows 0 lawns?

• $60

• $40

• $20

• $0

How much does John earn per lawn mowed?

• $15

• $10

• $20

• $25
