Rayne · Answer 1

17 cheques per month

Explanation:

ATM services and charges are same in both banks

so, ATM charges is ignore

lets calculate the break even in cheque drawing between both banks

Total cost = Fixed cost + Variable cost

Fixed cost = monthly charges

Variable cost = cost per check

For south trust bank the monthly charges is $11

cost of writing single check is $0

therefore,

Total cost = Fixed cost + Variable cost

lets use X to represent number of order

= $11 + 0 * X

For sun coast bank the monthly charges is $2.5

and $0.5 per check

therefore,

Total cost = Fixed cost + Variable cost

lets use X to represent number of order

= $2.5 + $0.5 * X

Equate both the equation

$11 = $2.5 + $0.5 * X

$8.5 = $0.5 * X

X = 17

so, the number of cheques to be drawn of south trust bank is 17 per month
