Mathematics: 69. suppose that you currently have one credit card with a balance of $10,000 at an annual rate of 24.00% interest. you have stopped adding any additional charges to this card and are determined to pay off the balance. you have worked out the formula bbn = b0r n − r(1 + r+r2 ++ r n−1), where b0 is the initial balance, bn is the balance after you have maden payments, r= 1 + i, wherei is the monthly interest rate, and r is the amount you are planning to pay each month. a. what is the monthly interest

i = 1,8087 %

r = 1.018

Step-by-step explanation:

For an effective annual rate j you have that the monthly interest rate can be related to it as:

$(1+i)^{12} = 1+j$

Solving for i:

$i=\sqrt[12]{1+j} -1$

replacing j = 24% => i = 1,8087 %

So growth rate r would be:

r = 1 + i = 1.018
