Question

Chapter 2.3, Problem 8OE

To determine

The conclusion about Jim’s first test score.

Expert Solution & Answer

Answer to Problem 8OE

77≤85.5

Explanation of Solution

Given:

The given statement is:

The second test score=First test score+8,

The third test score=88

Calculation:

The solution for the given statement can be obtained by:

Let Jim’s first test score=x

The second test score=x+8

The third test score=99

80≤Average of all subjectsNo. of subjects≤8980≤x+(x+8)+883≤89

Collect the terms

80≤2x+963≤89240≤2x+96≤267144 ≤ 2x ≤ 17172 ≤ x ≤ 85.5

Hence, Jim’s first test was between 77 and 88.5 inclusive.
