How to find subtotal and sales tax? give an example.

See explanation below.

Step-by-step explanation:

First, obtain the percentage of sales tax for a sale. Say it is 5%.

Then, obtain the sale prices, for two items say they are: $25.00 and $15.00.

Add the amounts together to obtain the subtotal:

$25.00 + $15.00 = $40.00, is the subtotal.

Multiply the amount by the percentage:

$40.00 * 5% =

40 * .05 = $2.00, is the sales tax

Add the tax to the subtotal to obtain the total amount to pay:

$40.00 + $2.00 = $42.00, is the total amount to pay.

Hope this helps :-)
