In the set of problem, assume that the data can be modeted by a straight line and that the trend continues indefinitely. Use two data points to find such a line and then answer the question. (See Example 1.)
Physical Science Ski resorts require huge amounts of water in order to make snow. Snowmass Ski Area in Colorado plans to pump at least 1120 gallons of water per minute for at least 12 hours a day from Snowmass Creek between mid- October and late December.* Environmentalists are concerned about the effects on the ecosystem. Find the minimum amount of water pumped in 30 days. (Hint: Let y be the total number of gallons pumped x days after pumping begins. Note that (0, 0) is on the graph of the equation.)
