Given:
Fixed cost to rent a moving van = $23
Additional cost = $7 per hour.
To find:
For $37, the maximum amount of time that a moving van can be rented for.
Solution:
Let the moving van be rented of t hours.
Total cost = Fixed cost + Additional cost

For $37, the total cost should be less than 37.



Divide both sides by 2.

Since maximum value of t is 2, therefore the moving van can be rented for maximum 2 hours.
Answer:
3 times rebate will maximize its revenue
Step-by-step explanation:
Given that a store has been selling 300 DVD burners sold per week at 350 each
A market survey indicates that for each $ 30 rebate offered to buyers, the number of units sold will increase by 60 a week.
If x times rebate is offered then units sold would be 300+60x
Thus original revenue
After rebate of x times 30 dollars we have
New revenue

Equate first derivative to 0 to get
x=
i.e. 3 times rebate will maximize its revenue
