5.Elaine was charged $195 interest for 1 month on a $1000 credit card balance. What was the monthly interest rate?
A) 20.5% B) 20% C) 19% D) 19.5%
My answer: D) 19.5%
Is it just me or does #5 seem like the interest rate should be 0.195 instead of 19.5%?? Because $1000*0.195=195 and that would be a lot more reasonable than 19.5%. I don't know...
I agree with your anwser of 19.5%.
195/1000 = .195
.195 * 100 = 19.5
So it is 19.5% D is the correct answer there.
