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

Hi ;-)
10 minutes for 2 songs = 5 minutes per song
10 : 2 = 5
By applying the <em>quadratic</em> formula and discriminant of the <em>quadratic</em> formula, we find that the <em>maximum</em> height of the ball is equal to 75.926 meters.
<h3>How to determine the maximum height of the ball</h3>
Herein we have a <em>quadratic</em> equation that models the height of a ball in time and the <em>maximum</em> height represents the vertex of the parabola, hence we must use the <em>quadratic</em> formula for the following expression:
- 4.8 · t² + 19.9 · t + (55.3 - h) = 0
The height of the ball is a maximum when the discriminant is equal to zero:
19.9² - 4 · (- 4.8) · (55.3 - h) = 0
396.01 + 19.2 · (55.3 - h) = 0
19.2 · (55.3 - h) = -396.01
55.3 - h = -20.626
h = 55.3 + 20.626
h = 75.926 m
By applying the <em>quadratic</em> formula and discriminant of the <em>quadratic</em> formula, we find that the <em>maximum</em> height of the ball is equal to 75.926 meters.
