Question

A landscaper rents a wood chipper for 4 days. The rental company charges $100 for the first day and $50 for each additional day. Write and graph a step function that represents the relationship between the number of days x and the total cost of the renting the chipper.

Answer 1

y=50x+100

Explanation:

The total cost, y is given by

y=100+50x where x is the number of days

When graphing, using y=mx+c, the gradient will be always 50 and at point when x=0, y=100 when x=1, y=150, when x=2, y=200 when x=3, y=250 and when x=4, y=300
