Assume that simple co. had credit sales of $282,000 and cost of goods sold of $166,000 for the period. it estimates that 1 percent of credit sales in uncollectible accounts when it uses the percentage of credit sales method and it estimates that the appropriate ending balance in the allowance for doubtful accounts is $3,900 when it uses the aging method. before the end-of-period adjustment is made, the allowance for doubtful accounts has a credit balance of $410.

Suppose that a paving company produces paved parking spaces (q) using a fixed quantity of land (t) and variable quantities of cement (c) and labor (l). the firm is currently paving 1,000 parking spaces. the firm's cost of cement is $3 comma 600.003,600.00 per acre covered (c) and its cost of labor is $35.0035.00/hour (w). for the quantities of c and l that the firm has chosen, mp subscript upper c baseline equals 60mpc=60 and mp subscript upper l baseline equals 7mpl=7. is this firm minimizing its cost of producing parking spaces?
