# Grade Point Average In many universities students are given grade points for each credit unit according to the following scale: A 4 points B 3 points C 2 points D 1 point F 0 point For example, a grade of A in a 3-unit course earns 4 × 3 = 12 grade points and a grade of B in a 5-unit course earns 3 × 5 = 15 grade points. A students grade point average (GPA) for these two courses is the total number of grade points earned divided by the number of units; in this case the GPA is ( 12 + 15 ) 8 = 3.375 .(a) Find a formula for the GPA of a student who earns a grade of A in a units of course work, B in b units, C in c units, D in d units and F in f units.(b) Find the GPA of a student who has earned a grade of A in two 3-unit courses, B in one 4-unit courses and C in three 3-unit courses.

To determine

(a)

To Find:

A formula for the GPA of a student.
