This problem confuse even the likes of me... Ho-Chi-Minh! :

If manufactured correctly, a basketball should bounce from 48 inches to 56 inches when dropped from a height of 6 feet. Determine the tolerance for the bounce height of a basketball and write an absolute value inequality for acceptable bounce heights.

Simply put, I don't understand!

the range is expressed as:

(-4) > x (the variable, in this case the bounce) > 4

Thank you, but I'm afraid the answer won't help me on a test!

Could you explain how you got that?

Well, first of all, you can't compare feet with inches as it is put.

So...

48/12 = 4, 56/12 = 4 2/3. So, when dropped from a height of 6 feet, it should bounce between 4' and 4'8"

l height of bounce l < 6 ft

If this is simply indicating the acceptable bounce range for a six foot drop, why do you need to convert? Without getting into physics, what bearing does the drop height have on this range. To set up the equation to show bounce height in relation to drop height requires you to figure acceleration and elasticity and a lot of other crap. Given that the 6 feet are a fixed part of the problem, isn't it just: 48" < x < 56"

?

(All < and > symbols should be taken as "or equal" and x is the acceptable bounce)

Not really a math dude.

That's what Ho-Chi thought but why do they make the answer so easy if that is what it is!?

What did your study buddy, little chairman Mao, get for an answer?

I dunno. Maybe the post saying you need to convert is right, maybe the six feet is there as a red herring. Or maybe you're supposed to convert feet to inches to show you're clever enough to make one conversion instead of two.
