A local retail store manager is considering whether to promote a leading brand in a non-perishable, frequently purchased product category during the last week of May.There have been no promotions for some weeks.Promotions are always executed as 10,000 coupons distributed via postal mail.Each coupon has a face value of 35 cents.The regular margin the retailer gets on the brand when it is not on promotion is $1.35 per unit. Based on past experience, the manager expects that 7% of the 10,000 coupons are redeemed.Printing and distribution costs for the coupons total $10 per thousand coupons.Coupon processing costs are 10 cents per redeemed coupon.What proportion of the sales in which a coupon is redeemed would need to be incremental (i.e., would not have occurred without the coupon) for the retailer to break even on the costs of the promotion?

Options:

66%

35%
