Winchesters community bank charges $6 per month plus 15 cents per check for the use of a standard checking account. Thomas had a checking account there for 8 months and was charged a service fee of 53.10. How many checks did he write during that period?

C'mon Jennyjen123 you can do this one! How many months? X how many $ per month =? When you get that answer, subtract it from $53.10. Divide the balance by .15 =? That is the number of checks.

I hope I'm not doing someone's home work for them... however my calculation says 34 Cheques.

Yes you are probably doing their homework. Give them tips and let them learn how to get the answer.
