Question: Kerry is ready to celebrate his birthday and wants to have three cakes with his age in candles on each of them. Candles come in boxes of 12 and cost $2.5 a box. If the candles cost $5, how old is Kerry? Think carefully first, then make a decision:
He needed 2 boxes of candles, because 5 / 2.5 = 2. He needed 24 candles because 2 x 12 = 24. He is 8 because 24 / 3 = 8. So the answer is 8.
