The average amount A (in pounds per person) of fish and shellfish consumed in the UnitedStates during the period 1992–2001 can be modeled by
A = (3.2x + 260)/(52x + 3800)
where x is the number of years since 1992.Rewrite the model so that it has only whole number coefficients. Then simplify the model.
