Question

16. In a college, some courses contribute more towards an overall GPA than other courses. For example, a science class is worth 4 points; mathematics is worth 3 points; History is worth 2 points; and English is worth 3 points. The values of the grade letters are as follows, A= 4, B=3, C=2, D=1, F=0. What is the GPA of a student who made a “C” in Trigonometry, a “B” in American History, an “A” in Botany, and a “B” in Microbiology?

A. 2.59
B. 2.86
C. 3.08
D. 3.33
E. 3.67

Answer 1

im clueless

Answer 2

so 2/3+3/2+4/4+4/4?

Answer 3

This question is basically a question on averages. You add up the values*points, and then divide by points. For example, suppose there was only a “C” in Trigonometry, a “B” in Microbiology. Trigonometry was worth 3 points, and a C has a value of 2. M.Biology was worth 4 points, and a B has a value of 3. So the GPA would be\[\frac{3*2+4*3}{3+4}=\frac{18}{7}\]Does this help?

Answer 4

yeah

Answer 5

Can you show me what the setup would be for the whole problem?

Answer 6

so 2*3+3*2+4*4+4*3/3+2+4+4

Answer 7

Answer 8

40/13 =3.08

Answer 9
