mainly need help on Step on steps 4-9

Hint You are looking for the formula that gives you the initial current grade. Do a reference cell to that formula \begin{tabular}{|l|l|} \hline \begin{tabular}{l} Step \\ \hline 9 \end{tabular} & Do a 2-variable data table with the final exam grade and the exira credit points that would show the range of grades. \\ \hline Hint You will have to figure out which is the row yariahle and which is the column variable. Remember that you are trying to find the INPUTS into the FORMULA that the reference cell (the one you put in A31) uses. [You should have used the C column final grade for the previous instructions, so the inputs would be in the C column.]) \\ \hline 10 & Change the format of the cells inside the data table to percent with zero decimal places. Apply the conditional format using the Green - Yellow - Red Color Scale. \\ \hline 11 Save and close WhatiF-DataTable-GoalSeek xilsx. Exit Excel. Submit your files as directed. \end{tabular} Hint You are looking for the formula that gives you the initial current grade.
