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.
