m = 2 + 2x
x + m = 26
so
x + 2 + 2x = 26
3 x = 24
x = 8
so
m = 2 + 16 = 18

A bank has two plans for checking accounts. With plan A the charge is $7.50 a month with no fee for each check. With plan B the charge is $3 a month plus an additional 20 cents for each check written.What is the least number of checks a customer must write each month in order for plan A to cost less than plan B?
when 750 = 300 + 20 c
20 c = 450
c = 22.5 so 22
20 c = 450
c = 22.5 so 22
