Final answer:
The tax rate on the boat is 0.5%.
Step-by-step explanation:
To find the tax rate, we can use the formula:
Tax rate = (Property taxes / Value of the boat) x 100%
Substituting the given values, we get:
Tax rate = ($375 / $75,000) x 100%
Tax rate = 0.005 x 100% = 0.5%
Therefore, the tax rate on the boat is 0.5%.
