Question

Chris uncle from japan promised to give him 42 g of gold .The local jewelry exchange will buy gold for $1286 per once.How much money can Chris get for selling the gold?

Answer 1

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 = $\frac{1286}{28.3495} \approx \ 45.3624$

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 = $42 \times 45.3624 \approx \ 1905.22$

Hence Chris will make $1905.22 by selling gold.
