Gold is alloyed with different metals to make it hard enough to be used in jewelry. The amount of gold present in a gold ally is measured in 24ths called karats. 24-karat gold is 100% gold. Similarly, 12-karat gold is 50% gold. 
How many ounces of 4-karat gold should be added to 8 ounces of 8-karat gold to make an amount of 6-karat gold? Graph equations on coordinate axes with labels and scales. *
