1.The store is selling lemons at $0.43 each. Each lemon yields about 2 tablespoons of juice. How much will it cost to buy enough lemons to make two 9-inch lemon pies, each requiring half a cup of lemon juice?

2.Sound travels about 750 miles per hour. If you stand in a canyon and sound a horn, you will hear an echo.

Suppose it takes about 3 seconds to hear the echo. How far away is the canyon wall, in feet?

Now let's generalize that result. Suppose it takesn seconds to hear the echo. How far away is the canyon wall, in terms of n?

3.You want to put a 4 inch thick layer of topsoil for a new 25 ft by 33 ft garden. The dirt store sells by the cubic yards. How many cubic yards will you need to order? The store only sells in increments of 1/4 cubic yards.
