Earnings and Rate of Change

The video tutorial explains how Mighty Mo earns money at a software company. He receives $100 for showing up and $10 per hour of work. The lesson covers creating a T-table to represent hours worked and earnings, plotting these on a graph, understanding the rate of change, and formulating a linear equation to describe the relationship. The tutorial concludes with a recap of the concepts covered.

What is the initial amount Mighty Mole receives just for showing up at work?

• $200

• $50

• $150

• $100

How much does Mighty Mole earn per hour of work?

• $5

• $20

• $10

• $15

What is the task given in the lesson?

• To explain the relationship between hours worked and earnings using a table, graph, and equation

• To calculate total earnings for a month

• To determine the best working hours

• To find the maximum earnings possible

In the T-table, what are the X and Y variables representing?

• X: Hours, Y: Earnings

• X: Earnings, Y: Hours

• X: Days, Y: Earnings

• X: Earnings, Y: Days

What is the earnings amount when Mighty Mole works for 3 hours?

• $120

• $130

• $140

• $150

What is the first point plotted on the graph?

• (0, 100)

• (1, 110)

• (2, 120)

• (3, 130)

What type of relationship is represented by the line on the graph?

• Exponential

• Quadratic

• Linear

• Logarithmic

What does the rate of change refer to in this context?

• The change in company policy

• The change in total earnings

• The change in earnings per hour

• The change in hours worked

How is the rate of change calculated?

• Difference between X and Y

• Sum of X and Y

• Change in Y divided by change in X

• Change in X divided by change in Y

What is the equation representing the relationship between hours worked and earnings?

• y = 100 + 15x

• y = 100 + 10x

• y = 100 + 5x

• y = 100 + 20x
