In the Sales Tax cell (cell H28), enter a formula that calculates the Sales Tax based on the following criteria: If the customer’s state (cell C12) is IL, then the sales tax will be 7.00 percent of the subtotal (cell H27). If the customer's state (cell C12) is NOT IL, the sales tax will be $0 (There is no sales tax for orders outside of IL). Hint: You will need to use an IF Function.
