a. Write the cost function:: C(x) = 100x + 100,000 where x is number of guitars
---------------------------------
b. Write the revenue function:: R(x) = 300x where x is number of guitars
-----------------------
c. Find the profit function.
Profit = Revenue - Cost
P(x) = R(x) - C(x)
P(x) = [ R(x) ] - [ C(x) ]
P(x) = [ 300x ] - [ 100x+100,000 ]
P(x) = 300x - 100x-100,000
P(x) = 200x - 100,000
The break even point is when the profit is 0 dollars. You don't lose any money. And you don't gain any money.
Solve 125x - 100,000 = 0
125x = 100,000
x = 800 (# of guitars made and sold)
Answer:
A. 20000
Step-by-step explanation:
45-36 = 9 so you add 1,000 * 9 to 11,000, which gets you 20,000
a. Use the inclusion/exclusion principle.
b. By definition of conditional probability,
He has a total of 7 Boards. he has 3 boards of his own and then you add the 4 additional boards that he has
