One hundred students were surveyed about whether they prefer Snap chat or insta gram. out of the 50 boys surveyed there were 40 boys who preferred insta gram. out of the 50 there were 30 girls who preferred snap chat. Assuming that all students have a preference, what percent of the girls surveyed prefer snap chat?

Solve the problem. a student earned grades of c, a, b, and a in four different courses. those courses had these corresponding numbers of credit hours: 4, 5, 1, and 5. the grading system assigns quality points to letter grades as follows: a = 4, b = 3, c = 2, d = 1, and f = 0. compute the grade point average (gpa) and round the result to two decimal places. 3.40 3.50 8.75 2.18
