Carlos Martin received a statement from his bank showing
a balance of $56.75 as of March 15. His checkbook shows a
balance of $87.37 as of March 20. The bank returned all the
cancelled checks but two. One check was for $5.00 and the
other was for $13.25. How much did Carlos deposit in his
account between March 15 and March 20?
87.37-56.75 = 30.62
5 + 13.25 = 18.25
30.62 - 18.25 = ?
