it has been established that 8.0x10^4 tons of gold (Au) have been mined. Assume gold cost $350 per ounce. Whats the total worth of the quantity of gold?
so first lets find out how much gold there is. 10^4=10,000so that means 8.0x10,000= 8,000. now we have to find out how much money that is. All we have to do is multiply 8,000 by 350. When multiplied you get $2,800,000
