What is the average cost per coupon redeemed if Paul achieves the $2\%$ redemption rate?

VECCMs (vitamin enhanced chocolate coated marshmallows) failed to gain distribution in most health food stores, but Paul was determined to pursue his dream of marketing a good-tasting snack food that would include minimum daily requirements of most vitamins and minerals. He sold them in 160z resealable bags through independent grocery stores throughout the Mid-Atlantic. Paul's Selling prices to wholesalers of $1.19 a bag resulted in a contribution margin before advertising and promotion of 31%. Wholesalers sold to retailers and retailers to consumers, earning margins of 22% and 50% respectively. Sales are currently 1,200 bags per week. Paul is considering distributing 1 million free standing insert (FSI) coupons for $0.20 off the regular price and expects to pay $3 per thousand for artwork and distribution. Each coupon redeemed will cost an additional $0.03 in processing fees. What is the average cost per coupon redeemed if Paul achieves the 2% redemption rate?
