Required: a-1. Assuming the company can satisfy the annual demand, calculate the contribution margin for each type of sleeve using the table below. a-2. How much operating profit could Williams earn if it were able to satisfy the annual demand? b-1. Compute the contribution margin for each sleeve per the constrained resource, direct labor. b-2. Which of the three product lines makes the most profitable use of the constrained resource, direct labor? c. Given the information so far, what product mix do you recommend? d-1. Calculate the contribution margin for each type of sleeve using the product mix recommended in requirement c. d-2. How much operating profit should your recommended product mix generate? e. Suppose that the company could expand its labor capacity by leasing a new stitching machine that will free up 2,160 direct labor hours per quarter. What is the maximum quarterly lease payment that Williams Gear would be willing to pay? f. Suppose the company selling the stitching machine is not quite sure without further analysis how many direct labor hours the new machine would free up. Regardless of the number of new hours, what is the maximum quarterly lease payment Williams Gear would be willing to pay?

The revenue function \(R(x)\) and the cost function \(C(x)\) for a particular product are given. These functions are valid only for the specified range of values. Find the number of units that must be produced to break even. \(R(x) = 200x - 2x^2\); \(C(x) = x^2 + 10x + 5425\), \(0 \le x \le 100\) The manufacturer must produce units to break even

PROBLEMS (Unless instructed otherwise, round answers to the nearest dollar. Interest rates are per annum unless otherwise specified.) Pe-1 (Lo2,4 GROUPWORK) - Various Time Value Situations Answer each of these unrelated questions. a) Fishbone Corporation sold a building with a carrying amount of $100,000 on the date of sale. Fishbone received as consideration a $240,000 non-interest-bearing note due on January 1, 2020. There was no established exchange price for the building, and the note had no ready market. The prevailing rate of interest for a note of this type on January 1, 2017, was 9%. At what amount should the gain from the sale of the building be reported? b) On January 1, 2017, Fishbone Corporation purchased 300 of the $1,000 face value, 9%, 10-year bonds of Walters Inc. The bonds mature on January 1, 2027, and pay interest annually beginning January 1, 2018. Fishbone purchased the bonds to yield 11%. How much did Fishbone pay for the bonds? c) Fishbone Corporation bought a new machine and agreed to pay for it in equal annual installments of $4,000 at the end of each of the next 10 years. Assuming that a prevailing interest rate of 8% applies to this contract, how much should Fishbone record as the cost of the machine? d) Fishbone Corporation purchased a special tractor on December 31, 2017. The purchase agreement stipulated that Fishbone should pay $20,000 at the time of purchase and $5,000 at the end of each of the next 8 years. The tractor should be recorded on December 31, 2017, at what amount, assuming an appropriate interest rate of 12%? e) Fishbone Corporation wants to withdraw $120,000 (including principal) from an investment fund at the end of each year for 9 years. What should be the required initial investment at the beginning of the first year if the fund earns 11%? Pa-2 (LO2,3,4 GROUPWORK EXCEL) - Various Time Value Situations Using Excel

Consider the Hamiltonian H of an electron in a spherically symmetric potential V(r) with an additional spin-orbit coupling given by (r)L.S where (r) is some spherically symmetric coefficient. Defining the total angular momentum vector operator J = L + S and noting that the full Hamiltonian is now of the form H = p^2/2m + V(r) + (r)LS, show that [H, L] = 0 and [H, S] = 0.
