To work this out you would first need to convert the percentage of 13% into a decimal. You can do this by dividing the percentage of 13 by 100, this gives you 0.13. This is because percentages are out of 100.

To work out the price of shipping and handling you would need to multiply the amount of $508 by the decimal of 0.13, this gives you $66.04. This is because we are working out 13% of $508.
