Ocean water contains 0.9 ounce of gold per ton. Method A costs $230 per ton of water processes and will recover 85% of the metal. Method B costs $270 per ton of water processed and will recover 65% of the metal. The two methods require the same investment and are capable of producing the same amount of gold each day. If the extracted gold can be sold for $400 per ounce, which method of extraction should be used? Assume that the supply of ocean water is unlimited.

Dawson Toys, Limited, produces a toy called the Maze with the following standards: Direct materials: 7 microns per toy at $0.33 per micron Direct labor: 1.1 hours per toy at $6.80 per hour During July, the company produced 5,000 Maze toys. The toy's production data for the month are as follows: Direct materials: 79,000 microns were purchased at a cost of $0.29 per micron. 35,250 of these microns were still in inventory at the end of the month. Direct labor. 6,000 direct labor-hours were worked at a cost of $43,200. Required: 1. Compute the following variances for July: Note: Indicate the effect of each variance by selecting "F" for favorable, "U" for unfavorable, and "None" for no effect (i.e., zero variance). Input all amounts as positive values. Do not round intermediate calculations. Round final answer to the nearest whole dollar amount. a. The materials price and quantity variances. b. The labor rate and efficiency variances. 1a. Material price variance 1a. Material quantity…

For the production of part R-193, two operations are being considered. The capital investment associated with each operation is identical. Operation 1 produces 2,100 parts per hour. After each hour, the tooling must be adjusted by the machine operator. This adjustment takes 15 minutes. The machine operator for Operation 1 is paid $24 per hour (this includes fringe benefits). Operation 2 produces 2,350 parts per hour, but the tooling needs to be adjusted by the operator only once every two hours. This adjustment takes 45 minutes. The machine operator for Operation 2 is paid $13 per hour (this includes fringe benefits). Assume an 8-hour workday. Further assume that all parts produced can be sold for $0.35 each. a. Should Operation 1 or Operation 2 be recommended? b. What is the basic tradeoff in this problem?

Electricity is produced with water according to the function: E = 5 + 5W-1W² where E = kilowatt-hour and W = gallons of water. Water costs $0.02 per gallon. Electricity can be sold on the grid for $0.10 per kWh (kilowatt-hour). How much water should be purchased?
