An item sells for $40. The sales tax on the item is 8%. What is the sales tax and total cost?

The sales tax is $3.2 and the total cost is $43.2.

Step-by-step explanation:

Multiply 0.08 by $40 to find the sales tax (8% is the same as 0.08)

Then add 3.2 (sales tax) to the regular price to find the total price.
