f(2) =-5
Answer:
A. Equation is 
B. Cost is $88
Step-by-step explanation:
A)
Suppose you rent for x hours and each hour costs $15.75
<u><em>How much would you need to pay?</em></u>

Moreover, there is a $25 dollar (fixed) deposit for renting, so that gets added to your payment. All in all, you have to pay 
This is the equation of renting a snowboard for x hours.
Equation is 
- Where x is the number of hours you rent the snowboard, and
- c is the total cost
B)
If you are renting from 8.30 to 12.30, you are basically renting for 4 hours.
To know how much it will cost, you simply plug in 4 into x (in the equation):

Cost is $88
Answer:
B
Step-by-step explanation:
Given that r is inversely proportional to s then the equation relating them is
r =
← k is the constant of proportion
To find k use the condition r = 16 when s = 3
k = rs = 16 × 3 = 48
r =
← equation of variation → B
