mary has y m of cloth.she used 2 m to sew a skirt.she used the remaining cloth to make 5 jackets.
(a) find the amount of material that was used to make each jacket in terms of y.
(b) if she has 17 m of cloth.how much material was used for each jacket?
a. Bal. = ym - 2m.
Amt per jacket=(ym-2m)/5 = m(y-2) / 5.
b. Amt per jacket = (17m-2m) / 5 = 15m / 5 = 3m.
Cloth Mary has = ym
used (skirt) = 2m
Used for jacket = 5
A.) ym-2m/5 or the substitute m(y-2)/5
B.)Substitute 17 to ym
(because that's the cloth Mary has)
