sbuck98 · Answer

You just multiply the percentage from the other number, and subtract that answer from the number

kayders1997 · Answer

C=R(T)where C=cost after tax r=regular cost before tax T=tax

kayders1997 · Answer

Sorry no C=cost of tax

kayders1997 · Answer

Than you need to subtract that from the cost after tax so you can find the original rate
