Question

To rent a bicycle, a bike shop charges a deposit plus an hourly rate. Martin can determine how much he will have to pay for rental lasting t hours by using the expression 5t + 16. What does the coefficient 5 represent?

a) Hourly rate for the bicycle
b) Total deposit amount
c) Fixed rental fee
d) Total rental cost for t hours

Answer 1

The coefficient 5 in the expression 5t + 16 represents the hourly rate for the bicycle rental.

Step-by-step explanation:

Martin can determine how much he will have to pay for bicycle rental lasting t hours by using the expression 5t + 16. In this expression, the coefficient 5 represents the hourly rate for the bicycle. The number 16 represents the deposit, which is a fixed amount paid regardless of how many hours the bike is rented.

The equation 5t + 16 is a linear equation in one variable, where t is the independent variable representing the number of hours the bike is rented, and the whole expression represents the dependent variable, which is the total cost of the rental. In this case, the coefficient next to the variable (t) is the amount that changes in relation to how long the bike is rented.
