Barney earns $24.75 in 3 hours if the amount that Barney earns varies directly with the number of hours, how much would he earn in 20 hours.

2x - 20 = 32 20 - 3x = 8 6x - 8 = 16 -13 - 3x = -10

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

Wrote and expression for the difference of p and 4
