calculate the total for each item

Is there a way you can add a column on the email so it calculates the total

for each item? Ex: 7 x $11.45 is $80.15

Then have a total for all items shown at bottom? So $80.15 + $47.00

=$127.15 (with note stating “Tax, if applicable, and freight are added to

an order)
