Real Math - My Son's Oat Milk

One of my boys has food allergies. A ton of them. So many that wife and I keep a list for OURSELVES posted in the kitchen. The latest and greatest food sensitivity seems to be to flax, which means my wife went looking for a replacement to his flax milk today. (Flax milk was already a replacement for coconut, which had replaced soy, which had replaced almond, which had replaced dairy. Tired yet?)

She tried using our Kitchen-Aid blender today, and got through the job, but it was quite under-powered for what she really needed, so we made the decision to buy one of those hardcore you-can-blend-an-iphone blenders.

When I got home from a meeting earlier, she asked me to do some math with her. Here was our conversation.

As we talked, I wrote down what she was saying, and put together 2 expressions to make a system.

Before I talk about Algebra, I just want to give her a shoutout for having AMAZING estimation skills, but really, check out those systems! I asked her if we could record before she asked me the real question, and I was HOPING, to get something worthwhile, but this is so cut and dry perfect it was like she set me up.
Next time your students ask about using systems in their lives, feel free to let them know about the little boy in Missouri and his mom making oat milk. :)
