What must you do to accept a solution in Goal Seek?

To accept a solution in Goal Seek, it is necessary to click the OK button in the Goal Seek Status dialog. When you use Goal Seek, the tool performs a series of calculations to find the input value that will result in the desired output. Once it has determined a solution, the Goal Seek Status dialog displays the result of its calculations. By clicking the OK button, you confirm and accept the proposed solution, which updates the input cell with the calculated value that achieves your goal.

The other options do not lead to accepting the solution within the Goal Seek functionality. Opening the summary report could provide insights into the process but does not accept the results; manually re-entering values would negate the purpose of using Goal Seek, which automates this process; and resetting all findings would clear your current solution instead of accepting it. Therefore, clicking the OK button is the critical step required to finalize and accept the solution reached by Goal Seek.
