You have $1,998.00 on a credit card with a 14.5% apr. you miss your minimum payment the first month and there is a late fee of $37.00. how much is your balance at the beginning of the second month?

There are 2 parts to this question.  1. One would be to calculate the interest based on your balance and 2. then to add the late fee.  Use the formula i = prt to calculate your simple interest. i represents the interest you will pay, p stands for the principal (balance on your credit card), and t stands for the period of time (related to a period of a year/annual percentage rate).  The $1998 balance times 0.145 times 1/12 gives the interest amount of $24.14.  So, $1998 + $24.14 + $37 = $2059.14 balance.  

Multiply 9 and 67. then multiply 3 with 67. lastly the answer that you got for 9x67 is to be subtracted by the answer you got for 3x67
