2x+x=105
3x=105
The answer is A
Answer:
- 
Step-by-step explanation:
= 
( cross- multiply )
6x = 5y ( divide both sides by 6 )
x = y
Then
← substitute x = y into the expression
= 
= 
= 
= 
× - 
= -
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)
Hope that helps.Have a nice day!! ^^
