Examples of Conditional Equations.
=
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 FIRST is not equal to 0, then
VALUE＝FIRST＋1 ⎟ FIRST. If FIRST＝0, then VALUE＝FIRST.
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 |
13%
26%
310%
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?
