Homework Help: Algebra! Help needed!

Posted by Celina on Monday, November 24, 2008 at 7:10pm.

I'll try posting this again since no one responded before.

Wow, this one is hard to explain...

First, I'll give you the info you need to solve the problem.

Tough Cell Batteries Battery Life in Hours

Lower Extreme: 84
Upper Extreme: 140
Lower Quartile: 97
Upper Quartile: 110.5
Median: 104.5

If you need more info after reading the question, just tell me and I can give you all of the numbers.

Here's the question that I need to solve:
Suppose that Mrs. Brewer puts new batteries of the brand you named in question 3 (Tough cell batteries) in all the calculators at the beginning of the school year. About when during the year will she need to have replacements available (so I'm assuming for the least amount of battery life)?

Thank you so much! Any help is appreciated!

The answer depends upon how many hours a day the calculators are run. If they are on all the time, clearly some will have to be replaced in 84 hours...less than 4 days.

What kind of information are you not giving us?
