The United States is China’s largest export market. Imports from China have grown from about $100 billion in 2000 to $540 billion in 2018. This growth has been approximately linear.
(a) Determine a linear equation that approximates this growth in imports in terms of t, where t represents the number of years since 2000.
(b) Describe the rate at which the imports from China are changing.
(c) Based on the answer to part (a), what is the predicted amount of imports from China in 2020?
(d) If this trend were to continue, in what year would imports from China be at least $750 billion?
