develop a model of a truck's annual maintenance expenses based on its weekly usage in hours.

If the truck's weekly usage is 15 hours, we should expect its annual maintenance expense to be: (Keep one decimal place)

Weekly Usage (hours) Annual Maintenance Expense 13 17.0 10 22.0 20 30.0 28 37.0 32 47.0 17 30.5 24 32.5 31 39.0 40 51.5 38 40.0
