You are on a treasure-diving ship that is hunting for gold
and silver coins. You reel in a
wire basket that contains gold
and silver coins, among other
things. The basket holds no
more than 50 pounds of
material. Each gold coin
weighs about 0.5 ounce, and
each silver coin weighs about
0.25 ounce. You want to know
the different numbers of each
type of coin that could be in
the basket. Write an inequality that models the weight in the basket.
