Question

Barn owls produce one pellet per day. Assume each pellet contains undigested material from 80 grams of biomass. Also, assume that one 40 gram vole can cause 50 cents of crop damage to a farm per season. If a Barn owl family of seven (2 adults and 5 young) lives on a farm for 12 weeks and feeds entirely on voles, how much will the farmer save in crop damages? Assume that young owls also produce one pellet a day.
