A pack of wild horses has a population that fluctuates due to ecological pressures. In 2013 their population was at its lowest point of 50 horses. In 2016 the population had rebounded to its largest number of 120. If the population oscillates between these lowest and highest numbers at regular intervals going forward, what would be a sinusoidal equation that could model this starting with the year 2013? Write a let statement defining your variable and a final statement.
