Use Solver to determine the maximum or minimum value of one cell by changing other cells. For example, you can change the amount of your projected advertising budget and see the effect on your projected profit amount.

**Example of a Solver problem**

In the following example, the level of advertising in each quarter affects the number of units sold, indirectly determining the amount of sales revenue, the associated expenses, and the profit. Solver can change the quarterly budgets for advertising (cells B11:E11), up to a total budget constraint of $40,000 (cell F11), until the value for the total profit reaches the maximum possible amount. The values in the decision variable cells are used to calculate the profit for each quarter, so the values are related to the formula in the target cell F15, =SUM(B15:E15).
