Answer:
a. Debit Allowance for doubtful debt $4,398
    Credit Accounts receivable $4,398
    Being entries to write off receivable due from Madonna Inc.
b. $739,480  before and after the write-off
Explanation:
When a company makes sales on account, debit accounts receivable and credit sales. Based on assessment, some or all of the receivables may be uncollectible.  
To account for this, debit bad debit expense and credit allowance for doubtful debt. Should the debt become uncollectible (i.e go bad), debit allowance for doubtful debt and credit accounts receivable.
The realizable value of accounts receivable before the write off is the net of the accounts receivable and the allowance for doubtful debt
=  $762,000 - $22,520
= $739,480
This amount remains the same after the write off as the write off will reduce the balances in both the allowance for doubtful debt account and accounts receivable.
 
        
             
        
        
        
Answer:
Itis better to take the case in hand of 207,000,000 millions
Explanation:
We need to calcualte the present value of a geometric annuity-due
 
 
g	0.05
r	0.04
C	4,515,432
n	26
n	26
 
 
  127,557,727.45 
As is an annuity due, we multiply by (1+r)
127,557,727.45 x (1+0.04) = 132,660,036,548
The present value of the 207,000,000 option is better as the annuity present value is around 130,000,000
 
        
             
        
        
        
Answer:
$11,508.25
Explanation:
your son will start college in 14 years, and the present value of his college tuition = $40,000 x 3.4651 (PVIFA, 6%, 4 periods) = $138,604
your daughter will start college in 17 years, so you need in today's dollars $138,604 
you will need to save enough money to cover both tuitions;
money required to cover your son's tuition = $138,604 / 21.015 (FVIFA, 6%, 14 periods) = $6,595.48
money required to cover your daughter's tuition = $138,604 / 28.213 (FVIFA, 6%, 14 periods) = $4,912.77
total annual savings = $11,508.25
