Lizzy: A mother is making her own bubble mix out of dish soap and water for her two-year-old son. The recipe she is following calls for 3 tablespoons of soap for every 1 cup of water. If the container she hopes to store the bubble mix in can hold 40 ounces of liquid, and there are 8 ounces in a cup of water, how many tablespoons of soap should she add to the container (assuming that the soap itself doesn't count towards the capacity of the container)?.
Me: Hmmm, let me think. I think this is the detailed solution:
The 40 - ounce container can hold 40 / 8 = 5 cups of water. This means that 5 * 3 = 15 tablespoons of soap should be used, since each cup of water requires 3 tablespoons of soap. Final answer: 15.
