Question 360590: I need help to set up a GPA equation please.
Richards GPA is 3.7 and he made the following statement recently. " I have earned 110 credits from my college and I earned at least an A- in each case." An A is equivalent to 4.0 and and A- is equivalent to 3.67. How many of the credits were A and how many were A-?
Assume x= the number of credits A
and y = the number of credits A-

Richards GPA is 3.7 and he made the following statement recently. " I have earned 110 credits from my college and I earned at least an A- in each case." An A is equivalent to 4.0 and and A- is equivalent to 3.67. How many of the credits were A and how many were A-?
Assume x= the number of credits A
and y = the number of credits A-
---------
Credits Equation: x + y = 110
Points Equation: 4x +3.67y = 3.7*110
------------------------------------
Multiply thru the credits equation by 4 to get:
4x + 4y = 440
------------------------------------
Subtract the Points Equation and solve for "y":
0.33y = 33
y = 100 (# of A- credits)
x = 10 (# of A credits)
