The total cost of the bracelet will be $96.
The number of charms will be 2.
Step-by-step explanation:
Given,
Cost per charm at Dayton Fine Jewelry = $17
Cost of bracelet = $62
Let,
x be the number of charms
y be the total cost
y = 17x+62 Eqn 1
Cost per charm at Cain Jewelers = $18
Cost of bracelet = $60
y = 18x+60 Eqn 2
For same cost;
Eqn 1 = Eqn 2
Putting x=2 in Eqn 1
Putting x=2 in Eqn 2
The total cost of the bracelet will be $96.
The number of charms will be 2.

<h3>Answer: 93 degrees</h3>
=======================================================
Explanation:
Check out figure 1 which is one of the attached images below.
In this diagram, I have angle A as 75 degrees and angle B as 51 degrees.
Angle C is therefore, C = 180-A-B = 180-75-51 = 54 degrees.
----------
Point D is somewhere between A and B such that it is on segment AB.
Figure 2 (also attached as an image) shows segment CD forming two angles DCB and ACD.
These are the blue and red angles respectively, such that the blue angle is twice as large as the red angle.
blue angle = 2*(red angle)
This is what it means when it says the ratio of the two angles is 2:1.
I have 2x as the blue angle and x as the red angle. We don't know what x is yet, but we do know that the x and 2x combine back to angle C = 54 degrees.
So,
(angle DCB) + (angle ACD) = angle C
(2x) + (x) = 54
3x = 54
x = 54/3
x = 18
Since x = 18, this means 2*x = 2*18 = 36
Therefore,
angle DCB = 2x = 36 degrees
angle ACD = x = 18 degrees
--------
Focus solely on triangle DCB. We found angle DCB = 36 degrees and we know that angle DBC = 51
The remaining angle y = angle BDC is...
(angle BDC)+(angle DCB)+(angle DBC) = 180
(y)+(36)+(51) = 180
y+87 = 180
y+87-87 = 180-87
y = 93
angle BDC = 93 degrees
Figure 3 shows the angles we found (basically I replaced x, 2x and y with their respective numbers).
