Answer:
Yes the sales tax is higher than 3%, it is actually 3.65%.
Step-by-step explanation:
If the price of the guitar that Max bought was $602 (without taxes) and he ended up paying $624 with taxes, then the taxes were $22 (= $624 - $602). The $22 represent 3.65% [= ($22 / $602) x 100] of the guitar's price, and yes it is less than $30.
