    So, The western Beach is losing sand, dunes beach is gaining sand. In a span of about 11 to 12 years

    So, we would get a constant slope when you plot the graphs so 2 less per year for western and 5 more per year for dunes so both would be linear

    can u check my work for Between which years will the beaches have approximately the same width? 11 and 12/2006-2007 Assuming these rates remain constant, what can you do to get a better approximation of when the two beaches will have the same width -2x + 100 = 5x + 20 100 - 20 = 7x 80 = 7x 80/7 = x x ~11.43 years
