Question

Parsons Bank offers two​ checking-account plans. The No Frills plan charges 2525 cents per check whereas the Simple Checking plan costs ​$66 per month plus 55 cents per check. For what number of checks per month will the Simple Checking plan cost​ less?

Answer 1

66 + 0.05c < 0.25c
66 < 0.25c - 0.05c
66 < 0.2c
66 / 0.2 < c
330 < c

simple plan checking will be less if there were 331 or more checks written
