Kim your equations are right.
C = 2m + 25 in formula 1 and C = 7m in formula 2
Equating them we have,
7m = 2m + 25
==> 5m = 25
==> m = 5
Therefore for 5 visits, the amounts are equal.
Cost by formula 1 for 30 days = 2(30) + 25
= 60 + 25 = 85$
Cost by formula 2 for 30 days = 7(30)
= 210$
Therefore formula 1 is cheaper for a month.
