A local dental practice decides to run a Groupon campaign. The campaign offered $$355$ worth of dental services $($such as teeth whitening$)$ for $$140.$ For the total campaign, $265$ 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 customers purchased $1\mathrm{.}5$ coupons. Let's assume that $20\%$ of new customers come back after the Groupon coupon visit. The dental practice estimates its cost of goods sold to be $45\%.$ Finally, the bill for the average Groupon customer was $$390.$ The dental practice negotiated a $\frac{50}{50}$ split with Groupon.

Calculate the revenue from the Groupon campaigit.
