In the supply-and-demand schedule shown above, the equilibrium price for portable music players is _____.$100
$150
$250
Answers
Answer:
$150
Explanation:
Equilibrium price occurs at the point when the supply and demand of the product equals.
For example: Quantity of pens demanded in the market is 250, and Quantity supplied in the market is 250 as well.
With the same logic we can conclude that: At $150 the demand and supply of music players equals hence, it is the equilibrium price.

x+y=178
0.1x+0.25y=29.8
Solve x+y =178 for x
Add -y to both sides
x+y+-y=178+-y
x= -y+178
Substitute -y+178 for x in 0.1x+0.25y=29.8
0.1x+0.25y=29.8
0.1(-y+178)+0.25y=29.8
Simplify both sides of the equation
0.15y+17.8=29.8
Add -17.8 to both sides
0.15y+17.8+-17.8=29.8+-17.8
0.15y=12
Divide both sides by 0.15
0.15y/0.15= 12/0.15
y=80
Substitute 80 for y in x = -y+178
x= -y+178
x= -80+178
Simplify both sides of the equation
x= 98
Answer: D
x=98 and y= 80

Direct variation
Explanation:
Given –2 + 4y + 2 = 8x.
To find the given expression –2 + 4y + 2 = 8x is direct variation or not.
If y varies directly as x, then y = kx.
If y varies inversely as x, then
⇒ –2 + 4y + 2 = 8x
Combine like terms together.
⇒ –2 + 2 + 4y = 8x
⇒ 4y = 8x
Divide both sides of the equation by 4, we get
⇒ y = 2x
Which is in the format of y = kx.
Thus y varies directly as x.
Hence, –2 + 4y + 2 = 8x is direct variation.

Answer:
The retail price of the shirt is $19.2 .
Step-by-step explanation:
As given
A shirt that has a wholesale price of $12 and is marked up by 60 percent .
60% is written in the decimal form
= 0.60
Markedup price = 0.60 × 12
= $ 7.2
Thus
Retail price of shirt = Wholesale price of shirt + Marked up price
Put all the values in the formula
Retail price of shirt = $12 + $7.2
= $ 19.2
Therefore the retail price of the shirt is $19.2 .
To do that, we first need to divide 12/100.
12/100 = .12
.12 x 60% = $7.20
$7.20 + $12.00 = $19.20
Hope this helped :)
