Answer 1

B

Explanation:

Answer 2

Eliminate answer choices C and D immediately, since we are not looking to solve for either x or x^2; rather, we want the weekly profit (y) when the company sells x items. Eliminate choice A, because we are not looking to calculate the profit squared. This process of elimination of unsuitable answers leaves us with answer choice B, in which y is the the weekly profit in thousands of dollars, y, when the company sells x items.
