Assume that a firm's marginal cost is $10 and the elasticity of demand is minus2. We can conclude that the firm's profit-maxi

inysia [295]

Answer:

Option A. $20

Explanation:

Marginal cost be MC, marginal revenue be MR and . We know that

MR = ∆TR ÷ ∆Q

or

MR = (P∆Q+Q∆P) ÷ ∆Q

Here,

P is Profit-maximizing price

or

MR = (P∆Q ÷ ∆Q) + (Q∆P ÷ ∆Q)

or

MR = P + (Q∆P ÷ ∆Q)

we can also write the above equation as

MR = $P + P(\frac{Q}{P})(\frac{\Delta P}{\Delta Q})$

also,

Price elasticity of demand PED = $(\frac{Q}{P})(\frac{\Delta P}{\Delta Q})$

or

MR = P + [ P ÷ (PED) ]

We know MR = MC

Therefore,

MC = P + [ P ÷ (PED) ]

(P − MC) ÷ P = −1 ÷ PED

Substituting the values provided in the question

MC = $10

PED = -2

we get

P = [ PED ÷ (1 + PED)] × MC

P = ( -2 ÷ -1) × 10

or

P =$20

hence,

Option A. $20

On January 1, Year 1, the Accounts Receivable balance was $30,600 and the balance in the Allowance for Doubtful Accounts was $3,

Radda [10]

Answer:

The net realizable value of the accounts receivable immediately after the writing-off the uncollectible is $26,900

Explanation:

The formula to compute the net realizable value of accounts receivable is:

Net realizable value = Balance of accounts receivable - Balance in the Allowance for Doubtful Accounts

= $30,600 - $3,700

= $26,900

The amount of uncollectible which is written off will not be deducted from the balance of accounts receivable as this amount is already included in Allowance for doubtful account.
