Suppose that during the period 1990-2001, U.S. imports of pasta increased from 280 million pounds in 1990 (t = 0) by an average of 45 million pounds/year. (a) Use these data to express q, the annual U.S. imports of pasta (in millions of pounds), as a linear function of t, the number of years since 1990. q(t) = (b) Use your model to estimate U.S, pasta imports (in millions of pounds) in 2005, assuming the import trend continued. million pounds
