The average annual per-person consumption (in pounds per person) A(t) and B(t) of two comparable food products, A and B, are modeled by the system shown to the right, where t is the number of years since 1970. Use substitution or elimination to predict when the consumption of product A will equal that of product B. What will be that consumption? y = A(t) = 1.03t + 24.39 y = B(t) = - 0.59t + 123.83 The consumption of product A will equal that of product B in the year (Round to the nearest year as needed.)
