Answer:
Advanced tickets=30 Day =20
Step-by-step explanation:
Put them into equations:
x=advanced
y=day
x+y=50
25x+15y=1050
to make it simpler re-arrange x+y=50
x=50-y
Then substitute into 25x+15y=1050
25(50-y)+15y=1050
Expand
1250-25y+15y=1050
Rearrange
25y-15y=1250-1050
Work the above out
10y=200
y=20
and then
20+x=50
meaning....
x=30
showing Advanced tickets=30 Day =20
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%.
