If the price of a textbook is $40 before tax is added on, and tax is 10%, what will the final price of the textbook be?
Digiron [165]

Answer:

soln,

price of textbook = $40

tax% = 10%

now,

tax amount = 10% of $40

= 10\100*40

= 10*4/10

= 40/10

= $4.

again,

final price = cost of textbook+tax

=$40+$4

=$44.

Step-by-step explanation:

so the total price of a Textbook is $40 which is 100% and the tax is 10% so you need to find tax from the price of the textbook which is 10% of the price of the textbook then add the price of the textbook with the tax amount which is the final cost .
