What Robert bought a used automobile for 150000. If the sales tax is 5 what will be the total that Robert had to pay for Tyne automobile?

If Robert bought a used automobile for $150,000 and the sales tax is 5%, the sales tax amount would be $150,000 multiplied by 0.05, which equals $7,500. Therefore, the total amount Robert had to pay for the automobile would be the purchase price plus the sales tax, resulting in $150,000 + $7,500 = $157,500.
