If markup is 60% of the cost, you have
... markup = 0.60×cost
... markup/0.60 = cost
... $207.20/0.60 = cost = $345.33
_____
If markup is 60% of the selling price, the other 40% is the cost. So, the cost is 40/60 = 2/3 of the markup.
... cost = (2/3)×markup = (2/3)×$207.20
... cost = $138.13
_____
Markup can be specified in terms of either selling price or cost. Those are the usual reference values; there could be others. When only the percentage is given, you don't have enough information to work the problem. You need to know what it is a percentage of. (Example problems in your text may tell you the expected interpretation.)
Answer:
35.26°
Step-by-step explanation:
If a cube has side length x
diagonal of the face = x×√2
The diagonal of the cube = x × √3
the angle between them is an acute angle in a right triangle,
opposite = x , adjacent = x×√2 , hyp. = x×√3
sin(angle) = x / ( x×√3
)
angle = sin^(-1) ( 1/√3) = 35.26
Answer:
32 CDs, 13 Videos
Step-by-step explanation:
You can represent this question using variables.
Let x = #CDs sold, Let y = #videos sold.
You can formula two equations with the information given:
3x + 7y = 187
x + y = 45
Substitute x into the equation above by reducing the equation below:
x + y = 45 -> x = 45 -y
Since we are now able to remove x from the equation, plug in your new value into the equation above.
3(45-y) + 7y =187
135 - 3y +7y = 187
135 + 4y = 187
4y = 52
y = 13
Knowing the value of y, simply plug in this y value to solve for x:
x + 13 = 45
x = 32
We can use the slope-intercept form of a line with the given slope and y-intercept. y = mx + b and m is the slope and b is the y-intercept, so it's easy to plug in the slope and y-intercept. y = 3x + 1
