Help with formulas please:

In cell I11, calculate the total amount spent on groceries using a credit card. The result will be negative.

In cell I12, calculate the average spent on groceries using a credit card. The result will be negative.

In cell I13, calculate the number of times groceries were purchased using a credit card during the month.

In cell F7, nest an AND function within an IF function to determine if the transaction was paid using a credit card and the amount of the transaction is less than -100.

If both conditions are met in the AND function, the function should return the text Flag. For all others, the function should return the text OK.

Copy the function down through cell F24.
