Accepted Solution

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