Percy paid $24.10 for a basketball. the price of the basketball was $22.99. what was the sales tax rate? 4.58%

For this case we can make the following rule of three:
 $ 22.99 > 100%
 24.10 $ > x
 Clearing x we have:
 x = (24.10 / 22.99) * (100)
 x = 104.8%
 Therefore, the sales tax is:
 104.8-100 = 4.8%
 
 the sales tax rate was:
 4.8%

That they are numbers and related to each other.
