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

Step-by-step explanation:

given;

the price of an item=$40

tax rate =8%

now ,final rate= price of an item+ 8%of price of an item.

so, finalrate= $40+ 8% of $40

=$40+8/100×$40

=$40+$3.2

=$43.2 ans

false

step-by-step explanation:

whenever we assume a point on a plane then according to geometry it will definitely have 2 dimensions and if it assumed in space then it will have 3 dimensions.

the first one is x^2+2x+2

the second one is x^2+4

the last one is x^2-4x+8
