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?
Each of Koby’s boxes contain 3 sparklers + 5 whistlers = <T>add(3, 5)=8 fireworks.
So in total, Koby has 2 boxes * 8 fireworks per box = <T>multiply(2, 8)=16 fireworks.
Cherie’s box of fireworks has 8 sparklers + 9 whistlers = <T>add(8, 9)=17 fireworks.
Koby and Cherie therefore have a combined total of 16 fireworks from Koby + 17 fireworks from Cherie = <T>add(16, 17)=33 fireworks.
