1) Students can purchase school lunches using one of two payment plans. Students can either make a payment of \( \$63 \) per month or they can purchase lunch daily for \( \$ 2.75 \) per lunch.
a) Using the two functions \( f(d) = 63 \) and \( g(d) = 2.75d \) to represent the two payment plans, What does the
coordinates of the point that is a solution of both functions mean?
b) Explain which is the better meal payment plan for a student to select?

2) The National Weather Service releases weather balloons from \(102\) sites around the United States and its territories twice each day. The height of the balloon is a function of the time t after the balloon has been released.
a) Make a table of the time \(t\) in seconds and the height of the balloon from zero to ten seconds. b) The weather balloon continues to rise until it bursts after \(100\) minutes. Graph the function and identify the domain and range. |
