Now, sum up all the costs calculated:
e x t S u b − t o t a l = € 21.00 + € 9.00 + € 56.00 + € 120.00 = € 206.00 ext{Sub-total} = €21.00 + €9.00 + €56.00 + €120.00 = €206.00 e x t S u b − t o t a l = €21.00 + €9.00 + €56.00 + €120.00 = €206.00

To calculate VAT, use the sub-total:
e x t V A T = 206.00 e x t € i m e s 0.135 = € 27.81 ext{VAT} = 206.00 ext{€} imes 0.135 = €27.81 e x t V A T = 206.00 e x t € im es 0.135 = €27.81

Finally, add the VAT to the sub-total to find the total bill:
e x t T o t a l b i l l = € 206.00 + € 27.81 = € 233.81 ext{Total bill} = €206.00 + €27.81 = €233.81 e x t T o t a l bi ll = €206.00 + €27.81 = €233.81
