Burglar Alarm

SafeT Systems charges $125 for installation of their burglar alarm system and a $35 per month fee.

Uprotect Systems installs their burglar alarm system for free, but charges more money per month than SafeT.

If the average burglar alarm user keeps an alarm system for 5 years, how much money should Uprotect Systems charge per month to generate a profit equal to SafeT’s over that 5 year span?

Explain.
