You can put this solution on YOUR website!
Given:
The focus is the number of checks so Let n = number of checks
Anywhere charges .15(n)
AccuCheck charges .72 + .09(n)
The questionis when is AccuCheck's plan < Anywhere's plan
Set this up as an inequality
.72 + .09n < .15n - subtract .09 from both sides
.72 < .06n - divide both sides by .06
12 < n or when n > 12
Check: Find a number that makes this true for example, when n = 13
.72 + .09n < .15n
.72 + .09(13) < .15(13)
.72 + 1.17 < 1.95
1.89 < 1.95 True!
