2. Units cost $0.50 each to produce an item and they sell for $3.00 each. The overhead in setting up production is $2,000.
a) Find the cost and the revenue functions.
b) Find the breakeven point. Also graph the cost and revenue functions and label the breakeven point.
c) How many units must be sold to yield a profit of $2,000?
d) Find the average profit function and the rate of change of the average profit when x=20 items.
a ) COST FUNCTION & REVENUE FUNCTION :
Cost fn. = FC + VC
Lets assume that the number of unit is X,
Given , Set up cost ( fixed cost ) = $ 2,000
VC per unit = $0.5
COST FUNCTION = 2,000 + 0.5X
Revenue fn. = selling price * quantity
Given , selling price = $ 3 per unit
REVENUE FUNCTION = 3X
b ) BREAK EVEN POINT :
BEP = FIXED COST / CONTRIBUTION PER UNIT
CONTRIBUTION PER UNIT = SELLING PRICE / UNIT ( - ) VARIABLE COST / UNIT
Contribution / unit = $ 3 - $ 0.5
= $ 2.5
BEP = $ 2,000 / 2.5
BEP ( UNITS ) = 800 Units
c ) UNITS TO BE SOLD TO EARN PROFIT OF $ 2,000
= FIXED COST + PROFIT TO BE EARNED CONTRIBUTION PER UNIT
= 2,000 + 2,000 / $2.5
= 4,000 / 2.5
= 1,600 UNITS
d ) Average profit function = profit function / X
profit function = revenue function - cost function
= 3X - 0.5X - 2,000
Avg profit function = 3X - 0.5X- 2,000 X
= 3 - 0.5 - 2000/X

(b) Find the number of shirts that need to be sold to break even. (c) Find the average rate of change of the profit function for a production level of 10...
The cost to produce q electric cat brushes is described by the function: C(q)= 10q^2+250q, where q is hundreds of units for volumes less than 2,000. The demand function for electric cat bushes is described by: P(q)= -q^2-3q+1280, where p represents price in dollars. 1.) What are the company's marginal cost and marginal revenue functions? 2.) Calculate the number of units that produces the maximum profit. What price should the company charge and what is the maximum profit it will...
A. Given cost and revenue functions and C(q) = 112q + 44000 and R(q) = -3q^2 + 2500q, how many items must the company produce and sell to earn a profit of 67,900? The company must produce _ items. B. Given cost and revenue functions and C(q) = 112q + 43000 and R(q) = -3q^2 + 2800q, how many items must the company produce and sell to break even? The company must produce and sell _ items.
Problem 1: A company produces an item at a per-unit cost of $1000 and a fixed cost of $50,000. The selling price is a linear function of number of items demanded as follows: p = 15,000 - 200x, x5 80 A. Find the per-unit selling price when the demand is 30. B. Find the revenue function and find the revenue when the demand is 30. C. Find the cost function and find the cost when the demand is 30. D....
A company estimates that it can sell 4, 000 units each month of its product if it prices each unit at $65. However, its monthly number of sales will increase by 5 units for each $0.10 decrease in price. The company has fixed costs of $500. The cost to make each unit is $4.40. Find the level of production that maximizes the company's profit. They should produce | units at a price of $ 1, which will yield a profit...
