Question 1193179: Suppose two groups in Grande Prairie sponsor river tours that include sightseeing and lunch. Group 1 charges a fixed fee of $120 plus $8 per hour, and Group 2 charges a fixed fee of $100 plus $10 per hour.
a. Write equations for the average cost per hour for each boat ride as a function of the rental time, in hours. Indicate what your variables represent in the equation.
b. Complete a table based on the 2 graphs. What do the graphs show about how the average cost changes for different ride times?
c.Is one group always the better choice? Explain.

You can put this solution on YOUR website!
1: y=8x+120; the fixed cost is the constant, x= the fee per hour.
2: y=10x+100

Group 2 is cheaper for fewer hours; G1 for more hours.
they are the same when the two equations are equal.
10x+100=8x+120
2x=20
x=10 hours and y for both would be $200,
