1. Coffee sales on the JU campus are at their highest in the winter, and lowest in the summer. In January (t = 0), the highest number ice cream cones are sold at 2800 cups. The sales are lowest in July (t = 6) when 1400 cups are sold. We will use a sinusoidal function to model ice cream sales. %3D Below is the graph of the sales of coffe, f(t), as a function of time, t in months. 4,000 3,500 3,000 2,500 2,000 1,500 1,000 500 10 12
