Question

hang's uncle from Japan promised to give him 21 g of gold. The local jewelry exchange will buy gold for $1152 per ounce. How much money can Chang get for selling the gold?

Answer 1

Chang can get $777.71 for selling the gold.

Step-by-step explanation:

To calculate the amount of money Chang can get for selling the gold, we need to first convert the weight of the gold from grams to ounces. There are 31.1 grams in an ounce. So, 21 grams of gold is equal to 21 / 31.1 = 0.6755 ounces of gold. Next, we need to multiply the number of ounces by the price per ounce. The price per ounce is $1152. Thus, Chang can get 0.6755 * $1152 = $777.71 for selling the gold.

Answer 2

Chang get $853.35 for selling the gold.

Step-by-step explanation:

To calculate how much money can Chang get for selling the gold we have to know the conversion between ounces and grams.

We know that 1 ounce is equivalent to 28.3495 grams.

Then, if Chang sold the 21 g that receive from his uncle, the amount of money he gets is:

`M=21\,g\,\cdot(1\,oz)/(28.3495\,g)\,\cdot (\$1,152)/(1\,oz)=(21*1,152)/(28.3495)=\$\,853.35`

Chang get $853.35 for selling the gold.
