Answer:
$11.25
Step-by-step explanation:
We have been you purchase a stereo that originally costs $250 but is marked 10% off. The sales tax is 5%.
First of all, we will find price of stereo after 10% off by finding 90% of $250.
[tex]\text{Price of stereo after sale}=\$250\times\frac{90}{100}[/tex]
[tex]\text{Price of stereo after sale}=\$250\times0.90[/tex]
[tex]\text{Price of stereo after sale}=\$225[/tex]
Now, we will find 5% of 225 to find amount of sales tax.
[tex]\text{Amount of sales tax}=\$225\times \frac{5}{100}[/tex]
[tex]\text{Amount of sales tax}=\$225\times 0.05[/tex]
[tex]\text{Amount of sales tax}=\$11.25[/tex]
Therefore, amount of sales tax would be $11.25.
