Answer
Sales tax: $30$ dollars
Total cost: $405$ dollars
Work Step by Step
To find the sales tax, multiply the purchase price by the tax percentage.
375 $\times$ 8% which is 375 $\times$ 0.08
375 $\times$ 0.08 = 30. So the sales tax is 30 dollars.
To find the total cost, simply add the purchase price plus the sales tax.
30 + 375 = 405.
So the total cost is 405 dollars.
