One common system for computing a grade point average (gpa) assigns 4 points to an a, 3 points to a b, 2 points to a c, 1 point to a d, and 0 points to an f. what is the mean of a student who gets an a in a 3-credit course, a b in each of two 2-credit courses, a c in a 3-credit course, and a d in a 2-credit course?

A student gets an A in 3 credits (4, 4, 4)

B in 2 credits (3, 3)

C in a credit (2)

D in a credit (1)

Add each number together and divide by the amount of numbers there are:

(4 + 4 + 4 + 3 + 3 + 2 + 1)/7 = (21)/7 = 3

The mean is 3, or a B

hope this helps

to find the unit price, we must figure out the cost of one item (in this case one dish towel).   to do this, we divide the total price ($7.92) by the number of items bought (for this problem it is 8, because there are eight dish towels in one pack).  

$7.92/8 = $0.99

therefore, the unit price, or the price of one dish towel, is $0.99.

hope this !
