Answer:

Ending Balance Due = $14,980.106

Total Interest = $780.106

Explanation:

solution

Total Interest and Ending balance due by the U.S. Rule are as given below

so interest is here for 70 day with 12 % of 21000

interest = 0.12 × 21000 ×  [tex]\frac{70}{360}[/tex]

interest = $490

so

payment = $2400 - $490

payment = $1,910

and adjusted balance  will be after that

adjusted balance  = $21,000 - $1,910

adjusted balance  = $19,090

and

on 100 day

Interest  =  0.12 × $19,090  ×  [tex]\frac{30}{360}[/tex]

Interest  =  $190.9

and

Payment  = $4,400 - $190.9

payment = $4209.1

So

adjusted balance  = $19090  - $4209.1

adjusted balance  = $14,880.9

and interest = $14,880.9 × 0.12  ×  [tex]\frac{20}{360}[/tex]

interest = $99.206

so Ending Balance Due  will be

Ending Balance Due = $14,880.9 + $99.206

Ending Balance Due = $14,980.106

and

Total Interest = $490 + $190.9 + $99.206

Total Interest = $780.106
