A salesperson in a recurring revenue firm is paid the equivalent of $2\mathrm{.}5$ months' sales revenue for each new customer added. The charge for the service is $$120$ per month, and providing the service costs the company $$50$ per month per customer. It costs $$25$ to initially hook up each new customer. What would be the effect on this month's expenses if the salesperson added fifty$-$five new customers this month?
