An Ounce of gold costs thirty-five times as much as an ounce of silver and an ounce of platinum costs twice as much as an ounce of gold. If you buy one more ounce of each metal it will cost $4,664.00. How much does an ounce of platinum cost?
Answer provided by our tutors
let cost per ounce of silver be $x , gold be $ 35x & of platinum be 70x
x + 35x + 70x = 4664
106x = 4664
x = 44
cost of platinum per once = 70*44 = $3,080
