What will Amanda pay if she rents a truck and drives 45 miles and splits the total coat with two friends?Explain

Question

The daily cost for a rental truck for a day and the rate is slop:1/2 and y-intercept:120.

Answer 1

I am assuming from the info given that the daily cost of the truck is cost = 0.5 X + $120.00

where x = the amount of miles driven and $120.00 represents the fixed charge of renting the truck.

so:

cost = 0.5 (45) + $120.00

cost = $22.50 + $120.00

cost = $142.50                since this is split three ways

 

cost per person = $142.50/3 = $47.50
