Question

Adriana is planning to ride the public bus to and from school this year. She wants to figure out how much it will cost her. The bus ride costs $1.25` each direction.
Let C represent the total cost of Adriana's bus rides and let r represent how many times Adriana rides the bus in one direction. Identify a quantity to be the independent variable and one to be the dependent variable for this situation.

I WILL MARK BRAINLIEST

Answer 1

Answer:

C is the dependent variable and r is independent

Step-by-step explanation:

Adriana can ride the bus any number of times she wants. No one is stopping her from doing that so 'r' becomes an independent quantity.

Whereas, the total cost for the bus rides depends on the number of times Adriana rides the bus and the relation is given as, C=1.25r

This is because it costs $1.25 each time she rides the bus in one direction
