Question

Stephen paid $340 for a $320 sofa. The extra amount was for tax. What was the percentage of tax for the sofa?

Answer 1

340-320 means 20 dollars for tax. Next we need to figure out what percent of 320 is 20 so we do 20/320 = .0625 so its 6.25% for tax... to check the problem do 320 x .0625 and it  equals 20.
