At4:00 a.m., it starting falling at a constant rate of 3 inches per hour, and then from 7:00 a.m. to 9:00 a.m., snow wasfalling at a constant rate of 2 inches per hour. It stopped snowing at 9:00 a.m. (Note: This problem models snowfalling by a constant rate during each time period. In reality, the snowfall rate might be very close to constant but isunlikely to be perfectly uniform throughout any given time period.)a. Write a piecewise linear function that models the depth of snow as a function of time since midnight.

An energy-efficient lightbulb, taking in 27.0 W of power, can produce the same level of brightness as a conventional lightbulb operating at power 100 W. The lifetime of the energy-efficient bulb is 10 000 h and its purchase price is $4.60, whereas the conventional bulb has lifetime 750 h and costs $0.50 per bulb. Determine the total savings obtained by using one energy-efficient bulb over its lifetime as opposed to using conventional bulbs over the same time period. Assume an energy cost of $0.20 per kilowatt-hour.
