Linear Equations in Real-World Scenarios Challenge

A car rental company charges a flat fee of $50 plus $20 for each day the car is rented. Write the equation that represents the total cost (C) in terms of the number of days (d) rented. What is the slope of the line?

• C = 50 + 30d; slope = 30

• C = 50 + 10d; slope = 10

• C = 20d; slope = 20

• C = 50 + 20d; slope = 20

A local gym has a membership fee of $30 and charges $10 per class attended. If you graph the total cost (C) against the number of classes (c), what is the equation of the line? How much would it cost to attend 5 classes?

A farmer sells apples for $2 each and has a fixed cost of $100 for supplies. Write the equation that represents the total revenue (R) in terms of the number of apples (a) sold. What does the y-intercept represent in this scenario?

• R = 2a - 100; y-intercept represents profit when selling apples.

• R = 2a; y-intercept represents total revenue when no apples are sold.

• R = 100 + 2a; y-intercept represents fixed costs.

• R = 2a + 100; y-intercept represents total cost when no apples are sold.
