Question

^{The cost of a pogo stick is $20, and the amount of tax due is $1.60. If the amount of tax is directly proportional to the cost of the storage unit, what is the tax rate?}

Answer 1

The tax rate is given by:

 

%Rate = (Tax/Price)×100%

 

So in this case the rate is

 

($1.60 / $20))×100% = (0.08)×100% = 8%
