We have the following formula:
Where:
• A = the money borrowed,
,
• r = the annual interest rate in decimals,
,
• n = the number of annual payments,
,
• t = the number of years.
In this problem, we have:
• A = $49000,
,
• r = 9.1% = 9.1/100 = 0.091,
,
• n = 12 (we have monthly payments),
,
• t = 9 years.
Answer
• A = 49000
,
• r = 0.091
,
• n = 12
,
• t = 9
