The cost function is an illustration of a linear function
The equation of the cost function is C(x) = 35 + 0.5x
The given parameters are:
-- the cost of renting a cooler
--- the rate per bottle
Assume the number of bottles in a cooler is x.
The cost function for the bottles in a cooler would be:
So, we have:
Evaluate the products
Hence, the equation is

Answer:
720 Arrangements
Step-by-step explanation:
Given the numbers could be from 0 - 9 and none of them is to be repeated.
The first place could be filled in 10 ways. (0 - 9)
The second place could be filled in 9 ways. (Excluding the one in the first place).
The third place could be filled in 8 ways. (Excluding the two numbers in the first two places).
Therefore, the total number of arrangements possible for the lock is: = 720 ways.
