Answer:
Chris will make $1905.22 by selling gold.
Step-by-step explanation:
Amount of gold Chris will have = 42 g
Current rate of gold = $1286 per ounce
We need to find the amount Chris will make after selling the gold.
Now we will first find Current rate of gold in grams.
We know that 1 ounce = 28.3495 grams.
So we can say that
28.3495 g = $1286
So 1 g = Rate of gold for 1 gram.
By Using Unitary method we get;
Rate of gold for 1 gram = ![\frac{1286}{28.3495} \approx \$45.3624](https://tex.z-dn.net/?f=%5Cfrac%7B1286%7D%7B28.3495%7D%20%5Capprox%20%5C%2445.3624)
Now we will find the amount for 42 g of gold
if 1 g = $45.3624
so 42 g = Amount of money for 42 g
Again by using Unitary method we get;
Amount of money for 42 g = ![42 \times 45.3624 \approx \$1905.22](https://tex.z-dn.net/?f=42%20%5Ctimes%2045.3624%20%5Capprox%20%5C%241905.22)
Hence Chris will make $1905.22 by selling gold.
