Answer:
$11.17
Step-by-step explanation:
Delilah's balance this month is... $550
APR is... 24.38% which is 0.2438
How many months are in a year?
12 months
So...
$550 x 0.2438 divided by 12 $11.17
x= money
y= percent of change
m= months in year
c= how much she is charged
x(y)/m=c
money times percent of change divided by the months in one year equal the amount of money Delilah is charged
