Koby and Cherie want to light fireworks. Koby has bought 2 boxes of fireworks while Cherie has just 1 box of fireworks. Koby’s boxes each contain 3 sparklers and 5 whistlers. Cherie’s box has 8 sparklers and 9 whistlers. In total, how many fireworks do Koby and Cherie have?
Thoughts? Step-by-step reasoning:
Each of Koby’s boxes contain 3 sparklers + 5 whistlers = 8 fireworks. So in total, Koby has 2 boxes * 8 fireworks per box = 16 fireworks. Cherie’s box of fireworks has 8 sparklers + 9 whistlers = 17 fireworks. Koby and Cherie therefore have a combined total of 16 fireworks from Koby + 17 fireworks from Cherie = 33 fireworks.
Thus, the answer is 33.
