a. true
b. false

False

Explanation:

In the modern days of technology, employers have a variety of ways to pay an employee apart from writing a check. Therefore, the statement is false. An employer can pay cash, or deposit the money to the employee's account, or provide a payroll debit card. However, providing through electronic mediums can minimize the costs and saving the time of employees to get the payment from the bank.

(a) Per unit material cost.

total cost of the mine = $1,190,000 (purchase cost) + $90,000 (restoration costs) + $200,000 (development costs) - $100,000 (salvage value) = $1,380,000

estimated tons of minerals = 60,000 tons

cost per ton = $1,380,000 / 60,000 tons = $23 per ton

(b) Total material cost of December 31, 2017, inventory

during 2017 extracted 30,000 tons and sold 22,000 tons, so the total inventory = (30,000 tons - 22,000 tons) x $23 per ton = $184,000

(c) Total material cost in cost of goods sold at December 31,

since the company sold 22,000 tons, the COGS = 22,000 tons x $23 per ton = $506,000
