We know the amount of copper is 85%, that means the rest is tin in the Alloy, so the tin is 15% of the Alloy then.
now, say "x" lbs is the total amount of the Alloy, and we know that 1 and 13/32 which is tin, is the 15% of "x", what the dickens is "x"?
2000 × 15% = 300
300 × 5 = 1500
2000 - 1500 = 500 population after 5 years
