Answer: 
Step-by-step explanation:
Given : Let f(n) represent the total annual cost of renting n video games.
A video game club charges a fixed annual membership fee of $20 and $2 per video game rented.
Then the total annual cost is given by :-

If the membership was increased by $15 the next year , then the total cost in next years will be :-

Hence, the function best represents the relationship between f(n) and n if the membership was increased by $15 the next year :

The time taken to get to the 4th can be obtained by dividing the distance given by the speed of the lift.
Distance, height from ground to 4th floor = 42 feets
Time taken to get to the 4th floor = t
Recall :
Time = Distance / speed
- We aren't given the speed of the lift ;
- Assume speed of lift is 7 ft/sec
The time taken to get to the 4th floor will be :
Therefore, to obtain the time taken, divide the distance or height of the 4th floor by the speed of the lift.
