Question

A rental bus company charges $56 a day for a bus as well as charging a one time fee of $15. Write an equation for the cost in dollars, as a fnction of the number of days,x

Answer 1

Hi!

$56 is charged each day for a bus, and x represents the number of days. $15 is the one-time fee (a fixed cost), so no variable goes beside that number. The x-value changes as the number of days increase and $56 is added on.The y-variable represents the total cost of renting the bus. In this case, the equation would be y = 56x + 15.
