Question 1124616
Well obviously Maple leaf offers the lowest monthly charge is no checks are written. If he does use checks however it all depends on how many! After 8 checks written with Maple leaf it becomes more expensive than Ontario.

Ontario trust with 8 checks = ${{{8}}} + ${{{0.50 * 8}}} = ${{{12}}}
Maple leaf with 8 checks = ${{{6}}} + ${{{0.75 * 8}}} = ${{{12}}}

Ontario trust with 9 checks = ${{{8}}} + ${{{0.50 * 9}}} = ${{{highlight(12.5)}}}
Maple leaf with 9 checks = ${{{6}}} + ${{{0.75 * 9}}} = ${{{green(highlight(12.75))}}}
