Expression ant the order of operations

It's not uncommon for students to ask, "When will I actually use this in my daily life?" When it comes to the Order of Operations, chances are, you've probably used this concept before.

For example, say you want to buy a $5 bottle of lotion for 10 family members and 4 friends from work. How much money do you need to budget? To figure this out, you need to use the Order of Operations:

5 * (10 + 4)

= 5 * 14

= $70

If you don't use the Order of Operations, your answer will be off:

5 * 10 + 4

50 + 4

= $54

Now it's your turn to develop your own "real-world" scenario that illustrates the Order of Operations. Your post should include the following:
