Suppose that a college student is taking three courses: a two-credit course, a three-credit course, and a four-credit course. The expected grade in the two-credit course is 3.5, while the expected grade in the three- and four-credit courses is 3.0.
What is the expected overall grade point average for the semester? (Remember that each course grade is weighted by its share of the total number of units.)

let x be the money she spent so that she can earn the free t-shirt.

35 is an outlier
