a person owes 1000 on credit cards that charge an interest rate of 2% per month. his much they owe in 6 months

That person will owe $ 1,120 in 6 months with the interest rate of 2% per month.

Explanation:
You must figure out the amount of money it is that will be added up every month. So you multiply: $1,000x0.02=$20
$20 is being added to what you owe per month. So, if you want to know how much you will owe in 6 months, then you will need to multiple the amount per month to how many months you haven’t paid anything: $20x6=$120
Once you have the amount that it would cost in 6 months, you add it to the amount you already owe: $1,000+120=$1,120

$1,000
x 0.02
————
$20

$20
x 6
——-
$120

$1,000
+ 120
————
$1,120
