Question

Luka and Gabby rent a tandem bike for $25/hr.Which value is the dependent variable? Which is the independent variable? Write an equation to represent the relationship between the number of hours, h, and the total cost of c.

Answer 1

See below ↓

Explanation:

Given

• rate of renting a tandem bike = $25/h
• h = number of hours
• c = total cost

Solving

• Clearly, as the number of hours does not depend on another variable, h is the independent variable
• Therefore, c is the dependent variable
• The equation is :
• ⇒ c = 25h

Answer 2

c = 25(h)

dependent variable : They must give $25 per hour.

independent variable: time is independent as no specific time given.

total cost = $25 * hours taken

c = 25 * h

c = 25(h)
