: Hello- I have recently returned to school and need help. It seems no one I know can remember Algebra to help me and I am having issues with the word problems, frankly they are starting to annoy me. My problem is as follows:I need to compare the price of Glad wrap to Press'n Seal. A roll of Glad wrap sells for $2.99. A roll of Press'n Seal sells for $3.79 or 5 cents a square foot. Press n'Seal sells for 10/3 times as much per square foot as Glad Wrap. What is the price of Glad wrap per square foot? I know I need to find the price of Glad per sq. ft. I have tried all the examples shown in chapter 5 and I guess I'm not sure what goes where anymore. I would appreciate ANY help and BIG Thank you ahead of time. Also any suggestions on learning to decipher word problems?? I have along ways to go. This question is from textbook Practical Business Math Procedures

Word problems: Read carefully and symbolize the information as you
read so you won't have to read the whole problem more than once or
twice.
-------------
Your Problem:
Glad = 299 cents per roll
---------
Press = 379 cents per roll
Press price = 5 cents per sq. ft.
Press has 379/5 = 75.8 sq ft in a roll
------------
Press price = (10/3)Glad price
Substitute:
5 cents = (10/3)Glad price
Multiply both sides by (3/10) to get:
(3/10)5 = Glad price
Glad price = 3/2 cents per square ft.
-----------------
You probably see that some of the information I put down
was useless. You don't know till you get to the answer.
