A borrower borrows on a five year loan $5,000 from a bank at 10% and will pay back the loan in twenty equal $ payments (quarterly) at the end of each time period. How much is each equal payment, how much principal and interest is paid back, and how much interest is paid back? (Note-since the borrower repays the loan quarterly, the % is divided by 4 and the exponent ( 5 years) is multiplied by 4). Also since it is a loan(payment), calculate the factor and then divide the factor into the $5,000, do not multiply the factor by the $5,000. - 8. A borrower borrows on a five year loan $5,000 from a bank at 10% and will pay back the loan in sixty equal $ payments (monthly) at the end of each time period. How much is each equal payment, how much principal and interest is paid back, and how much interest is paid back? (Note-since the borrower repays the loan monthly, the \% is divided by 12 and the exponent ( 5 years) is multiplied by 12). Also since it is a loan(payment), calculate the factor and then divide the factor into the $5,000, do not multiply the factor by the $5,000. (.10/12)=8.333333333 03=(.008333333) 5. A borrower borrows on a five year loan $5,000 from a bank at 10% and will pay back the loan in five equal \$ payments (annually) at the end of each time period. How much is each equal payment, how much principal and interest is paid back, and how much interest is paid back? (Note-since the borrower repays the loan annumlly, the \% is divided by 1 and the exponent ( 5 years) is multiplied by 1). Also since it is a loan(payment), calculate the factor and then divide the factor into the $5,000, do not multiply the factor by the $5,000. - 6. A borrower borrows on a five year loan $5,000 from a bank at 10% and will pay back the loan in ten equal \$ payments (semiannually) at the end of each time period. How much is each equal payment, how much principal and interest is paid back, and how much interest is paid back? (Note-since the borrower repays the loan semi-annually, the % is divided by 2 and the exponent ( 5 years) is multiplied by 2). Also since it is a loan(payment), calculate the factor and then divide the factor into the $5,000, do not multiplv the factor bv the $5.000
