Question 785343
During the period 2210—2220, Martian imports of mercury (from the planet of that name) increased from 580 million kg in 2210 (t = 0) by an average of 50 million kg/year.
(a) Use these data to express h, the annual Martian imports of mercury (in millions of kilograms), as a linear function of t, the number of years since 2010.
h(t) = 580+50t 
(b) Use your model to estimate Martian mercury imports in 2239, assuming the import trend continued.
h(29) = 580 + 50*29 = 2030 million kg
