Profit made by jeweler from buying and reselling ounces of gold is 140.89 per ounce
<u>Solution:</u>
Given that
Price at which jeweler buy gold = 1235.55 per ounce
Price at which jeweler resells gold = 1376.44 per ounce
We need to calculate profit.
Buying price of 1 ounce of gold = 1235.55
Reselling price of 1 ounce of gold = 1376.44
<em>Profit = Reselling price – buying price</em>
So profit on 1 ounce of gold = 1376.44 – 1235.55 = 140.89
Hence profit made by Buying and Selling gold will be 140.89 per ounce

Answer:
The rectangular 5 x 10 table.
Step-by-step explanation:
To find which table the office manager needs to get so he can sit more people at it is decided by one factor, the perimeter. The rectangular one, which is 5 x 10 the perimeter is (5 x 2) + (10 x 2) = 10 + 20 = 30. The circular one can be calculated by the equation
where d = 8. Putting
x 8 in my calculator and it comes out approximately at 25.132, having a less amount of perimeter space to work with, making the rectangular table the way to go.
