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?
How many boxes of candles did Kerry need? ** He needed 2 boxes of candles, because 5 / 2.5 = <<5/2.5=2>>2
How many candles did Kerry need? ** He needed 24 candles because 2 x 12 = <<2*12=24>>24
How old is Kerry? ** He is 8 because 24 / 3 = <<24/3=8>>8
