Asked by Trish
Bronze is an alloy that is made of zinc, tin, and copper in a specified proportion. Suppose an order is placed for 1000 pounds of bronze. The amount of tin in this order of bronze is two times the amount of zinc, and the amount of copper is 10 pounds more than 15 times the amount of tin. Find the number of pounds of zinc, tin, and copper.

z + t + c = 1000
t = 2 z
c = 15 t + 10 = 30 z + 10
z + 2z + 30z + 10 = 1000
solve for z, then substitute back to find c and t
t = 2 z
c = 15 t + 10 = 30 z + 10
z + 2z + 30z + 10 = 1000
solve for z, then substitute back to find c and t
