A

A local dental practice decides to run a Groupon campaign. The campaign offered $$365$ worth of dental services $($such as teeth whitening$)$ for $$135.$ For the total campaign, $240$ coupons were sold. We estimate that $85\%$ of the coupons will be redeemed, that $35\%$ of the coupons will be redeemed by existing customers and that, on average, Groupon fustomers purchased $1\mathrm{.}5$ coupons. Let's assume that $21\%$ of new customers come back after the Groupon coupon visit. The dental practice estimates its cost of goods sold to be $50\%.$ Finally, the bill for the average Groupon customer was $$390.$ The dental practice negotiated a $50/50$ split with Groupon.

Calculate the Groupon campaign profit$/$loss $(+/-).$
