Question 836294
A bank offers two checking-account plans. Their anywhere plan charges 30 cents per check, whereas their Acu-checking plan costs $1.20 per month plus 20 cents per check. For what number of checks per month will the Acu-checking plan costs less? Let N represents the number of checks.
-------
Anywhere plan: Cost(N) = 30N cents for N checks.
-----
Acu-check plan: Cost(N) = 120 + 20N for N checks in one month
----
Solve:
120+20N < 30N
120 < 10N
12 < N
-----
Acu plan costs less when # of checks is greater than 12.
