Price of computer = $755.00
Sales tax = 5%
Final price of computer = 755 + [tex]755 \times \frac{5}{100}[/tex]
= 755 × [tex]\frac{105}{100}[/tex]
= $792.75
APR = 17.25 % yearly=8.625%(Semi Annualy)=[tex]\frac{17.25}{12}[/tex]% monthly
Total price of computer including APR = 792.75 (1+ [tex]\frac{8.625}{100}[/tex])= 792.75 × [tex]\frac{108.625}{100}[/tex] = 792.75 × 1.08625=$861.124
You have to pay this money in six months.
Money paid by me in each month including APRand interest of $ 50 = [tex]\frac{861.124}{6}+50=143.52[/tex] +50=$ 193.52
Money paid by me in sixth month, if i miss a payment in the fifth month as an installment of computer= $193.52+$39= $232.52
So,Total Interest charged in sixth month =50+39+APR of each month= 232.52 - 132.125 = $100.395
