this is the last one 45 people cashed checks at bank A on Monday. Of these 80% of these already had accounts at bank A. onethird of the people who did not already have an account opened, opened an account Monday. how many people opened an account monday? how do i figure that out please?

0.8 * 45 = 36
45  36 = 9
1/3 * 9 = ?
