There’s plenty of fun to be had at an amusement park.

 

In fact, many families look forward to the time when they can go vacationing together at theme parks such as Six Flags in the United States; PortAventura in Tarragona, Spain; Pleasure Beach Theme Park in the United Kingdom; or hundreds of others around the world. There is a lot to do at an amusement park, including playing games of skill and chance, going on thrilling rides, and eating carnival food.

In this Project Connection you will use linear systems to model three problems set in the context of amusement park activities. Go to the Unit 4 Project and complete the Module 7: Lesson 3 component.

 
Going Beyond

Deciding what to eat is a choice that seems simple, but it can have a powerful influence over your health. There is quite a bit of information available online about the foods in restaurants. You can search on the Internet using the keywords “fast food calories” to find websites that show you information about the content of menu items from a variety of restaurants.

Some people think that fast food should be avoided all together, and some people think that is it not a big deal if it is eaten in moderation. What do you think? Find a website using the keywords described in the preceding paragraph, and create a system of equations that you would use to convince someone that there is either a high risk or a low risk of eating French fries. (You may choose another menu item rather than French fries.)

For this task, you will need at least two unknowns and two equations to graph, so you can decide if you want to look at calories and sodium or any other combination of data you will find online. (Of course, by now, you know that all systems of equations must have at least two unknowns and two equations.)
