For the project, I am going to calculate how much money I spend on m&ms each year. Every week I eat half of a glass cup of m&ms (the bigger glass cup on the left.)
Here are the dimensions of the glass cup.
Using the math above I found the volume of half the bigger cup and then how many cups of m&ms fit into the glass cup. It was not hard because the glass was in the shape of a cylinder.
Normally, I buy the package of m&ms shown below.
Using the math above, I found out how many packs I buy each year and how expensive it is. Next, I'm going to see if buying a bigger sized package will be more or less expensive.
Here is the bigger sized package below.
Using the math above, I found out how many packs of the bigger size package I would need per year. Then, I found the cost per year.
Surprisingly, it would be more expensive to buy the bigger package of m&ms. By buying the smaller package, I save $32.02 per year.
The next step of this project was to figure out how much material is used to make both sizes of the m&ms packaging.
Using the math above, I found out the amount of material used to make each sized package. Each year, by buying the smaller package, I save 264 square inches of material.
By buying the 42 oz package, I save $32.02 and 264 square inches of material each year.
