Linear Functions Review 83

Ben and Julia rented a truck from the same company to move to college. Ben drive 150 miles and paid $64.95 while Julia drove 84 miles and paid $45.15. What is the slope and what does it represent in context to the situation.

• m = 0.30; it represents the cost per mile.

• m = 0.30; it represents the initial fee for the moving truck

• m = 19.95; it represents the initial fee for the moving truck

• m = 3.33; it represents the cost per mile.
