Anita has 4,128 ice cream sticks. She can make a model of a house using 86 sticks. She can make a model of a castle using 96 sticks. If she makes nothing but model houses, how many can she make using all of the ice cream sticks?
Since she is making only model houses and no castles, we can exclude the number 96 from our equation. Since you want to know 86 x __ = 4,128, you need to divide. 4128/86= 48.
