The expression that gives the number of Jackets that can be made from a fabric of 1634 yards will be found as follows:
let the number of jackets be x.
the total length of material required to make x jackets cannot exceed 1634 yards, it can be equal to or less than 1634. Thus, the expression will be given as follows:
amount required to make one jacket is 378,hence:
378x≤1634
x≤4.32275
approximating the above we get:
x≤4
