The tax rate is 8% .
Step-by-step explanation:
Here we have , Luke went to Best Buy and bought a Sphero Mini. The Sphero cost $49.99 if he paid a total of $53.99, We need to find what is the tax rate. Let's find out:
Let tax rate be x% in the Sphero cost $49.99 . Now , Amount of tax paid is given by :
⇒ [tex]\frac{49.99(x)}{100}[/tex]
According to question , Amount of tax paid is given by :
⇒ [tex]53.99-49.99[/tex]
⇒ [tex]4[/tex]
Equating both we get :
⇒ [tex]\frac{49.99(x)}{100} = 4[/tex]
⇒ [tex]x= \frac{4(100)}{49.99}[/tex]
⇒ [tex]x= 8[/tex]%
Therefore , The tax rate is 8% .
