Answer:
1. Think of something that all kids like. To come up with a formula, think of other kids you have seen and what they eat. So observe, you saw 10 kids either eat fruit, goldfish, or cereal.
2. Lets say fruit = f, goldfish = g, cereal = c.
f + g + c = 10
3. The formula answers how many kids ate fruit, goldfish, and cereal. This helps you know what the kids will like when you babysit.
4. Yes, because you have seen 10 kids eat that kind of food, so you know that the kids you will watch will also like that.
5. Yes, because if the formula adds up with the problem, the units make sense.
