Question 343435: A pound of tin is worth $1 more than a pound of copper. Four pounds of tin are mixed with 6 pounds of copper to make a bronze that sells for $3.65 per pound. How much is a pound of tin worth? Answer by solver91311(24713) (Show Source):

The value of 4 lbs. of tin must be . The value of 6 lbs. of copper must be . 4 lbs. of tin plus 6 lbs. of copper must make 10 lbs of bronze, which, at $3.65 per pound must be worth $36.50.
And the value of the tin plus the value of the copper must equal the value of the bronze (assuming, as you can only do in the very contrived world of mathematics problems, that the two metals mix themselves into an alloy without the intervention of a workman who demands a wage or a factory that has overhead costs). So:
