### Lift capacity: 75S + 125B <= 750

Could someone help me with this ?

$75S + 125B\leq 750$

The capacity in pounds of the lift used by a roofing company to place roofing shingles and buckets of
roofing nails on rooftops is modeled by the formula shown, where S represents packs of shingles and B
represents buckets of nails. Use the formula to find (a) the largest number of shingle packs that can be
lifted, (b) the largest number of nail buckets that can be lifted, and (c) the largest number of shingle
packs that can be lifted along with three nail buckets.

What did you get for S when you made B as small as you could?
