Means: If A is greater than 7 and is less than or equal to 15, then

B＝ 2 x A ÷ 6＋C. Otherwise, B＝3 x A＋10＋C.

Means: If

A or B, but not both, equals 0, then T＝W x (A + B).

Otherwise,

T = W x A x B. In other words,

When

A＝0 and B≠0, T＝W x B.

When

A≠0 and B＝0, T＝W x A

When

A＝0 and B＝0, T＝0.

When

A≠0 and B≠0, T＝W x A x B.

Example: Nested IF Functions. An IF function can be used as the

argument of another IF function. This is called

nesting. Suppose a

corporation uses a rating system to determine salary. Employees are

rated on a scale from 1 through 3, and are given the following annual

percent raise based on their rating:

Rating Percent Salary Increase

10%

The Solver equation to calculate an employee’s new salary is based on

his or her rating and old salary. What would be the new annual salary

for an employee with a rating of 2 who currently earns $27,500

annually?
