Rick took his family to a major league baseball game.

Question

Rick took his family to a major league baseball game. He gave his son $100 to buy food and drinks for the group. Hot Dogs cost $3.50 each, beer cost $8.00 each, and soda costs $5.00 each. His son returned with $25.50 in change, and Rick was arrested for sending a nine year-old to buy beer, but that's neither here nor there. There were 8 beverages total in the order. how many hot dogs, beers, and sodas were purchased?

Answer 1

There is one solution to this problem but I am going to give you hints instead.

 

Let h = number of hot dogs

Let b = number of beers

Let s = number of sodas

 

3.50h + 8b + 5s = 100-25.50 = 74.50

 

b + s = 8

 

There is only a combination of values b and values s that you plug in the first equation above which makes value h MEANINGFUL. By meaningful I mean, do youthink you can buy 1.35 hotdogs?

 

There are very few combinations to try so you can do it manually.
