Joseph Biggs owns his own sno-cone business and lives 30 miles from a California beach resort. The sale of sno-cones is highly dependent on his location and on the weather. At the resort, his profit will be $120 per day in fair weather, $10 per clay in bad weather. At home, his profit will be $70 in fair weather and $55 in bad weather.
