Parker and his three friends went trick-or-treating together. If Parker got 11 pieces of candy, and each of his friends got three times as much candy as he did, how many pieces of candy did Parker and his friends get in all?
Each of his friends got 3*11 = 33 pieces
11 + 3(33) =
No. of pieces Parker got candy = 11
Each of his friends got these times candy as he did.
So each of his friends got candy = 3 * 11 = 33
No. of pieces of candy get Parker and his friends = 11 + 33 + 33 + 33 = 110
