Stainless steel is an alloy (mixture of metals) that many forks, knives, and spoons are made of. To make the stainless steel, a company mixes 4.5 pounds of chromium and 2 pounds of nickel with 18.5 pounds of iron.
a. A regular spoon weighs about 25 grams. Explain how you could find out what percentage of the spoon's weight is due to chromium. How much is this in grams?
b. A pound of iron costs $32, while a pound of nickel is $8 per pound. Chromium costs $145 per pound. How much does it cost the company to make 60 pounds of stainless steel? Explain your thinking.
