Use an IF function in cell H18 to calculate the commission rate for the total sale for order 1. The commission rate is 2% for all sales that total more than $10 and 1% for all sales that total more than $5. No commission is paid on sales that total $5 or less. Reference the threshold levels (cells F13 and F14) in your logical tests for your IF function and the commission rates (cells G13 and G14) as your "value_if_true" and "value_if_false" arguments. Use appropriate relative and absolute references.
