Please choose the correct answer and show the process:

1. Find the equation of the tangent line to y = 2 ln x at the point where x = 8.
y = x/2 - 1 + ln 2
y = x/2 - 1 + 2 ln 2
y = x/4 - 1 + ln 2
y = x/4 - 2 + 6 ln 2
y = x/8 - 1 + ln 2
y = x/8 - 1 + 2 ln 2
y = x/8 - 1 + 3 ln 2
none of these

10. Acme estimates marginal revenue on a product to be 200q-1/3 dollars per unit when the level of production is q units. The corresponding marginal cost is 2q dollars per unit. Suppose the profit is $250 when the level of production is 1 unit. What is Acme's profit when 8 units are produced?
