A school typically sells 500 yearbooks in a year for $50 each. The economics class does a project
and discovers that they can sell 125 more yearbooks for every $5 decrease in price. The revenue for
yearbook sales is R(x) = (500+ 125x)(50 - 5x).

Evaluate the following expression 1/3^2

Determine whether the points (–3,–6) and (2,–8) are in the solution set of the system of inequalities below. x ? –3 y < 5? 3x + 2 a. the point (–3,–6) is not in the solution set, and the point (2,–8) is in the solution set. b. neither of the points is in the solution set. c. the point (–3,–6) is in the solution set, and the point (2,–8) is not in the solution set. d. both points are in the solution set.

I’m really confused and need to learn this
