What is the final rate cost of a item that is $40 after 8% tax applied

$43.20

Step-by-step explanation:

First, find the tax.

Multiply the tax rate by the cost of the item.

tax rate * item cost

The tax rate is 8% and the item costs $40

8% * 40

Convert 8% to a decimal. Divide 8 by 100 or move the decimal 2 places to the left.

8/100=0.08

8.0–> 0.8–> 0.08

0.08*40

Multiply

3.2

The tax is $3.20

Now, add the tax on to the cost of the item.

cost of item + tax

The item costs $40 and the tax is $3.20.

$40 + $3.20

Add

$43.20

The cost of the item after tax is $43.20

$43.2
