An air conditioner outlet finds that if it sells x air conditioners per month, its costs will be C (x) = 220 + 202, 500 and its revenue will be R(x) = -3x2 + 2020x (both in dollars). %3D %3D You must show your work for full credit on this problem. a. Find the outlet's break-even points. b. Find the number of air conditioners the outlet should sell to maximize profit, and the maximum profit. Recall that Profit = Revenue - Costs. %3D c. Explain the method you used to determine the number of air conditioners.
Permutations and Combinations
If there are 5 dishes, they can be relished in any order at a time. In permutation, it should be in a particular order. In combination, the order does not matter. Take 3 letters a, b, and c. The possible ways of pairing any two letters are ab, bc, ac, ba, cb and ca. It is in a particular order. So, this can be called the permutation of a, b, and c. But if the order does not matter then ab is the same as ba. Similarly, bc is the same as cb and ac is the same as ca. Here the list has ab, bc, and ac alone. This can be called the combination of a, b, and c.
Counting Theory
The fundamental counting principle is a rule that is used to count the total number of possible outcomes in a given situation.
