3 divided by 21 = 7
7*10 = 70!

If you assume that the original price of the jacket equals X, that means that when it was on sale, the equation to finding the price after the 30% sale would be (1-0.3)X=21 (since 30% of X would mean that Keiko should've paid 70%). That would simplify to 0.7X=21. Therefore, the original price (X) will be $30.

Chang and Cal both collect pearls. Chang has three more pearls in her collection than Cal. Write an expression to represent the

natta225 [31]

Let x be the number of pearls in Chang's collection. Let y be the number of pearls in Cal's collection.

Chang has 3 more than Cal, so x = y + 3.
Adding both collections would be x + y. It's easier to have an expression in one variable, so we will substitute what we had written about Chang in for x.
(y + 3) + y = 2y + 3.
