So you could say, well, this is going to be equal to question mark over 100, the part of 100. Part = percent × p a r t = p e r c e n t × base. Hence the word problem on percent can be solved by first converting it into mathematical expression and then solving for the variable.
Use The Formula C = P + Rp To Find The Total Cost Of The Shoes, Where C Is The Total Cost, P Is The Price, And R Is The Sales Tax Rate.
Base = part ÷ percent = p a r t ÷ p e r c e n t. A = r ⋅ b ⇒ p e r c e n t = r a t e ⋅ b a s e. X/100 is called the rate.
