IBP Inc. is considering establishing a new machine to automate a meatpacking process. The machine will save $50,000 in labor annually. The machine can be purchased for$200,000 today and will be used for 10 years. It has a salvage value of $10,000 at the end of its useful life. The new machine will require an annual maintenance cost of$9000. The corporation has a minimum rate of return of 10%. Do you recommend automating the process

Jagjit Company designs and builds retaining walls for individual customers. On August 1, there were two jobs in process: Job 93 with a beginning balance of $8,750 and Job 94 with a beginning balance of$7,300. Jagjit applies overhead at the rate of $8 per direct labor hour. Direct labor wages average$18 per hour.

Data on August costs for all jobs are as follows:

$$\begin{array}{lrrrr} & \text { Job 93 } & \text { Job 94 } & \text { Job 95 } & \text { Job 96 } \\ \hline \text { Direct materials } & \$ 950 & \$ 4,500 & \$ 3,300 & \$ 1,300 \\ \text { Direct labor cost } & 2,160 & 5,400 & 2,610 & 900 \end{array}$$

During August, Jobs 95 and 96 were started. Job 93 was completed on August 17, and the client was billed at cost plus 40%. All other jobs remained in process.

1. Calculate the number of direct labor hours that were worked on each job in August.

2. Calculate the overhead applied to each job during the month of August.

3. Prepare job-order cost sheets for each job as of the end of August.

4. Calculate the balance in Work in Process on August 31.

5. What is the price of Job 93?

The annual income from a rented house is $24,000. The annual expenses are$6000. If the house can be sold for $245,000 at the end of 10 years, how much could you afford to pay for it now, if you considered 9% to be a suitable interest rate

A firm plans to buy a machine costing $600,000. It has a residual value of$25,000 and an expected useful life of six years. The firm's management estimates the total income generated from the machine to be $300,000. Calculate the average rate of return of the machine.

Write a function that represents the situation. Your starting annual salary of $35,000 increases by 4% each year.

$$\begin{array} { l } { \text { If } \phi \text { is an isomorphism from } Z _ { 4 } \oplus Z _ { 3 } \text { to } Z _ { 12 } , \text { what is } \phi ( 2,0 ) ? \text { What } } \\ { \text { are the possibilities for } \phi ( 1,0 ) ? \text { Give reasons for your answer. } } \end{array}$$

If the distance from the North Pole to the South Pole along Earth's surface is 20,000 km, what is the circumference all the way around our planet? (1) 5000 km (2) 10,000 km (3) 20,000 km (4) 40,000 km

Use a graphing utility to graph the functions f, g, and h in the same viewing window. $f(x)=x^{2}, \quad g(x)=-2 x+5, \quad h(x)=f(x) \cdot g(x)$

Nova Products has a $5$ year maximum acceptable payback period. The firm is considering the purchase of a new machine and must choose between two alternative ones. The first machine requires an initial investment of $\$ 14,000$ and generates annual after-tax cash inflows of $\$ 3,000$ for each of the next $7$ years. The second machine requires an initial investment of $\$ 21,000$ and provides an annual cash inflow after taxes of $\$ 4,000$ for $20$ years. a. Calculate the payback period for each machine.

Give a reason for your answer in each. Assume that all variables represent integers. Does 7 | 56?

A cobalt-iron alloy is desired that has a saturation magnetization of $1.47 \times 10^{6} \mathrm{A} / \mathrm{m}$. Specify its composition in weight percent iron. Cobalt has an HCP crystal structure with c/a ratio of 1.623. Assume that the unit cell volume for this alloy is the same as for pure Co.

A machine with a book value of $80,000 has an estimated five-year life. A proposal is offered to sell the old machine for$50,500 and replace it with a new machine at a cost of $75,000. The new machine has a five-year life with no residual value. The new machine would reduce annual direct labor costs from$11,200 to $7,400. Prepare a differential analysis dated April 11 on whether to continue with the old machine (Alternative 1) or replace the old machine (Alternative 2)

You toss a pebble into a pool of water and watch the circular ripples radiate outward. You find that the function r(x) = 12.5x describes the radius r, in inches, of a circle x seconds after it was formed. The function $A(x)=\pi x^{2}$ describes the area A of a circle with radius x. Find $(A \circ r)(x)$ when x = 2. Interpret your answer.

Find the derivative of the function. f(y) = sinh(sinh(3y))
