Answer:
It costs $1,465.00 to rent the truck for 13 days.
Explanation:
I am making some assumptions. The 505 is the weekly cost and the 160 is the cost over 1 week?
y = 160d + 505
y is the total cost
505 is the cost for 1 week
160 is the cost for every day over 1 week
y = 160(6) + 505 (13-7 = 6 This is the number of days over a week that we must pay for
y = 960 + 505
y = 1465
It costs $1,465.00 to rent the truck for 13 days.
