Question
Chapter 1, Problem 1.72E
Interpretation Introduction
Interpretation:
The average grade using equation 1.32 if the scores on a 10-point quiz are 5, 5, 5, 5, 10, 10, and 10 is to be calculated.
Concept introduction:
Grade average is a measure of a student's achievement in academics at a college or university level and it is calculated by dividing the total number of points of grade obtained by the total number attempts made by a student. A student’s grade point average results in a mathematical mean or average of all final grades.

a =b+ cd lne
In order to solve the equation above for d, you must:
Step One
Add the same expression to each side of the equation to leave the term that includes the variable by itself on the right-hand side of the
expression:
-b ta =-bv +b+ cd Ine
Step Two
Multiply both sides of the equation by the same expression:
x(a - b) = xcd Ine
The resulting equation is:
