The minimum monthly payment for Andrew's credit card is 2% of his balance or $20, whichever is higher. If Andrew's balance at the end of his last billing cycle was $870, what is his minimum monthly payment?

OpenStudy (parker.goodbar):

A.$7.20 B.$17.40 C.$4.80 D.$20.00

OpenStudy (andrewishere):

And the cycle is a year right?

OpenStudy (parker.goodbar):

yes

OpenStudy (parker.goodbar):

sorry i disconnected @AndrewIsHere

OpenStudy (andrewishere):

it ok :)

OpenStudy (andrewishere):

Hmm the question is a bit confusing to me. Does he get billed 20% every $20 or every month with a minimum of $20

OpenStudy (parker.goodbar):

2% of his balance or $20, whichever is higher

OpenStudy (andrewishere):

ok this is what I would do

OpenStudy (andrewishere):

\[(2\div100)($870)\]

OpenStudy (andrewishere):

Can you figure it out?

OpenStudy (parker.goodbar):

i think it is 20 but i dont know

OpenStudy (andrewishere):

\[2\div100 = 1/50 \]

OpenStudy (andrewishere):

Now multiply 1/50 to $870 and you get 87/5 or $17.4

OpenStudy (andrewishere):

So the answer is B

OpenStudy (parker.goodbar):

oh ok thanks
