You limit your attention to the following two production options: you can produce plastic utensils or helmets. In the "utensils" case your estimat ann revenue $25,000, while production will cost you $8,000. However, in your "helmets" option, you expect to sell 2000 helmets every year at $10 each and the average total cost of every helmet will be $3. What is your accounting ?profit if you decided to produce helmets

A doctor is on contract to a medium-sized oil company to provide medical services at remotely located, widely separated refineries. The doctor is considering the purchase of a private plane to reduce the total travel time between refineries. The doctor can buy a used Learjet 31A now for $1.1 million or wait for a new very light jet (VLJ) that will be available 3 years from now. The cost of the VLJ will be $2.1 million, payable when the plane is delivered in 3 years. The doctor has asked you, his friend, to determine the present worth of the VLJ so that he can decide to buy the used Learjet now or wait for the VLJ. The MARR is 15% per year and the inflation rate is projected to be 3% per year. (a) What is the present worth of the VLJ with inflation considered? (b) Which plane should he buy?

A jewelry maker incurs costs for a necklace according to C(x) =29x+1650. If the revenue function for the necklaces is R(x) = 59x how many necklaces must be sold to break even? necklaces Electronic equipment manufacturer Dynamo Electric, Inc. makes several types of surge protectors. Their base model surge protector has monthly fixed costs of $1040. This particular model wholesales for $13 each and costs $6.50 per unit to manufacture. (a) Write the function for Dynamo's monthly total costs. C(x) = A manufacturer sells belts for $13 per unit. The fixed costs are $2500 per month, and the variable cost per unit is $8. (a) Write the equations of the revenue R(x) and cost C(x) functions. (b) Write the function for Dynamo's monthly total revenue. R(x) = R(x) = C(x) = (b) Find the break-even point. It takes units to break even. (c) Write the function for Dynamo's monthly profit. P(x) = (d) Find the number of this type of surge protector that Dynamo must produce and sell each month to break…
