A coal mine purchased 3 years ago for $7 million was estimated to contain 4,000,000 tons of coal. During the past 3 years the amount of coal removed was 21,000, 18,000, and 20,000 tons, respectively. The gross income obtained in these 3 years was $257,000 for the first year, $320,000 for the second year, and $340,000 for the third year. What is the cost depletion allowance for year 1.
A company manufactures three products 1, 2, and 3. Each product requires production time in three
departments as shown below:
PRODUCT DEPARTMENT 1 DEPARTMENT 2 DEPARTMENT 3

- How do I answer this, please? Acme Parts runs a small factory and employs workers who are paid one of three hourly rates depending on their shift: first shift, $17 per hour; second shift, $18.50 per hour; third shift, $22 per hour. Each factory worker might work any number of hours per week; any hours greater than 40 are paid at one and one-half times the usual rate. In addition, second- and third-shift workers can elect to participate in the retirement plan for which 3% of the worker’s gross pay is deducted from the paychecks. Write a program that prompts the user for hours worked, shift, and, if the shift is 2 or 3, whether the worker elects the retirement (1 for yes, 2 for no). Display: Hours worked Shift Hourly pay rate Regular pay Overtime pay Total of regular and overtime pay Retirement deduction, if any Net pay.arrow_forwardAt the beginning of month 1, Finco has $400 in cash.
