Problema Solution
you want to make a rectangluar banner that is 18 feet long. you have no more than 48 feet of trim for the banner. what are the possible widths of the banner
Answer provided by our tutors
let 'w' be the width of the banner
2*18 + 2*w <= 48
36 + 2w <= 48
2w <= 48 - 36
2w <= 12
w <= 12/2
w <= 6
so the banner’s width must be 6 feet or less.
