Answer:
The absolute decrease was of 33 million.
The relative decrease was of 22.45%.
Step-by-step explanation:
Absolute change
The absolute change is the number of CD's sold is the number of CD's sold in 2010 subtracted by the numbers of CD's sold in 2009.
The number is negative, which means that there was a decrease.
114 million - 147 million = -33 million
The absolute decrease was of 33 million.
Relative change
The relative change is the absolute change divided by the initial value.
So -33/147 = -0.2245
Which means that the relative decrease was of 22.45%.
Answer: 195
Step-by-step explanation:
(0.3x + 66) + (0.1x + 36) = 180. ( 180 because thats the angle of a straight line)
0.3x + 0.1x + 66 + 36 = 180
0.4x + 102 = 180
0.4x = 180 - 102
0.4x = 78
x = 195
In this problem, you would be dividing
