Opportunity Cost Excel Calculator - CFO.U - Teen

Description
This tool was created following an outing with our youngest daughter.

We had just finished an errand to fix her car. What a good feeling to check off one of our weekend to dos. A friend recently told her about a new coffee trailer nearby. We drove over to check it out. The parking lot with the trailer had a number of other “food carts” in it. They work like this. You park your car, walk up to order at one of the trailers and then your order will be delivered to your car. This order and delivery system combines Portland’s food cart chic with drive-in like service.

Michelle walked to the coffee trailer to order while I stayed in the car listening to music and relaxing. 35 minutes later (Michelle claims it was only 25) she walked back to the car. She is empty handed - her drink will be delivered to the car when it's ready. 10 minutes later (Michelle claims it was only a few minutes), her $4.00 drink arrives. Oops, it was $ 5.00 with tip.

She was happy. I, was appalled. As a parent, I now had the urge to teach - which resulted in this tool.
