Marco rented a small moving van. The moving company charges $40 a day for up to 5 days. The input is the time, in days, and the output is the total cost. This mapping diagram shows the inputs and outputs of the rental cost.

Input is time, this is your x-values

output is the total cost, this is your y-values.

in the question above "this mapping diagram shows ... " so i'm not sure if there more to the question or what the question actually is, but if you have to create a mapping, you will create a list of x values for days and y values for corresponding total cost.

Day 1 cost $40 (1,40)

Day 2 cost $80 (2, 80) ($40 per day for 2 days = 40 (2) = $80

Day 3 cost $120 (3, 120) ($40 per day for 3 days = 40 (3) = $120

hope this answers your question. : - )
