~Solving inequalities~

Hello everybody :-)

I'm pretty good at Algebra, and always have been... but I am not so great when it comes to word problems.
Here is what I need help with:

>>>
The length of a rectangular yard is 50 ft., and it's perimeter is less than 170 ft. Describe the width of the yard.
>>>

I do know this:
The width is less than 70ft. (because 50*2=100 and 170-100=70)
Therefore, the width is 70/2=35.

Is that all the question wants? Am I supposed to write a compound inequality?

Thanks for any help.

1 answer

2L + 2 W <170
L + W < 85
50 + W < 85
W < 35
however W can not be less than zero so
0 < W < 35
