Hello there, I am struggling to understand this word problem I received for my math homework. I find it hard to understand my teacher and they did not explain this concept to me so I am really unsure how to solve it.

Any help would be so greatly appreciated as I have scoured the internet and YouTube and have not found a similar problem such as this one. (Attached)
