Question

Daisy is buying a video game in the shop. The price before tax is $21, and after sales tax is $24.74. What is the sales tax plied to the video game? Round to the nearest hundredth

Answer 1

Recall that:

`\text{salesprice}=\text{originalprice+taxes.}`

Therefore Daisy pays:

`24.74-21=3.74\text{ dollars}`

in taxes for the videogame.

Now, recall that to determine the percentage that a represents from b we use the following expression:

`(a)/(b)\cdot100.`

Therefore, the sales tax applied to the videogame is:

`\frac{3.74\text{dollars}}{21\text{dollars}}\cdot100\approx17.81`

percent.

Answer: The tax applied to the videogame is 17.81%, in this case, the sales tax is 3.74 dollars.
