Question 1124619: Hello! I have used this site Before and it was incredibly useful therefore I was wondering if I can get help for one more question:
Darius saved $500 and wants to open a chequing account. Ontario Trust charges $8 per month, plus $0.50 per cheque. Maple Leaf Savings charges $6 oer month, plus 0.75 per cheque. Which bank offers the lower monthly charge?
It would be great if I can get some help with this, I dont know if the $500 has meaning or if it’s just there to throw you off. Thank you for your time!

You can put this solution on YOUR website!
It depends upon the number of checks.
The charges are equal at some point when the two
$8+$0.50x=$6+$0.75x, x the number of checks written that month
$2=$0.25x
x=8 checks.
Fewer than 8 checks, and Maple Leaf Savings is cheaper
Greater than 8 checks, and Ontario Trust is cheaper.

The $500 is irrelevant, at least to this question.
