Yes, I know I should do my own work and such, but I really don't get some of these word problems; I did all of them but three.
I'm really sorry for bothering the forum, but I didn't know where else to get help from, my Pre-Calculus teacher basically just assigns us a chapter to read and then expects us to be able to do the assignments and tests. Well, that may do it for some people, but not for me.
If you have read this far, thank you so much!
These are the word problems I have left to do:
Sales on baseball caps average 31000 per game when they are priced at $2.50 each. For each .50 increase, sales drop by 2000; what price would bring in the maximum revenue?
A rectangular piece of cardboard is measured to be 25 inches by 39 inches, it is then made into a box by cutting equally sized squares from each corner and folding it up. What can the maximum volume be?
I'm currently figuring this one out, but any help will be appreciated:
The perimeter of a rectangle is 36 inches. With the width becoming doubled and the length being increased by 21 inches, the new perimeter is 92 inches. What are the measurements of the length and width?
Thank you again so much!
