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:$5408
Step-by-step explanation:
The first company offers a straight commission of 5% of the sales. This means the salary or income is 5% of sales made.
The second company offers a salary of $260 per week plus 4% of the sales. This means salary or income
= $260 +4% of 260
= 260 + (4/100)×260
= 260 +(0.04×260)
=260+10.4 = $270.4
Let x = the amount of sales you would have to sell in a week in order for the straight commission offer to be at least as good
5% of x should be greater than or equal to $270.4
0.05x = 270.4
x = 270.4/0.05 =$5408
The sales should be greater than or equal to $5408
That would be 13/10 or 1 3/10
AE = AC = 4
m<CAB = 60 (equilateral triangle)
m<CAE = 90 (square)
m<BAE = 150 (= 60 + 90)
Triangle BAE is isosceles since AB = AE;
therefore, m<AEB = m<ABE.
m<AEB + m<ABE + m<BAE = 180
m<AEB + m< ABE + 150 = 180
m<AEB + m<AEB = 30
m<AEB = 15
In triangle ABE, we know AE = AB = 4;
we also know m<BAE = 150, and m<AEB = 15.
We can use the law of sines to find BE.
BE/(sin 150) = 4/(sin 15)
BE = (4 sin 150)/(sin 15)
BE = 7.727
