Question 758337: I am having trouble solving this problem, please help. Thank you.
A pound of tin is worth $2 more than a pound of copper. Two pounds of tin are mixed with 8 pounds of copper to make bronze that sells for $4.15 a pound. How much is a pound of tin worth?
Answer by josgarithmetic(39617) About Me  (Show Source):
You can put this solution on YOUR website!
Copper price = m dollars per pound
Tin price = m+2 dollars per pound

Mix 2 pounds of tin with 8 pounds of copper:
Account for cost, 2%2A%28m%2B2%29%2B8%2Am
and highlight%28%282%28m%2B2%29%2B8m%29%2F%282%2B8%29=4.15%29 to account for price.

Solving for m will give the price for the copper, per pound.
Add 2 and this is the price for the tin.
