The number of CDs the students at your high school bought in 2008 is 100
<h3>How to predict the number of CDs?</h3>
The graph of the question is added as an attachment
From the graph, we have the following highlights:
- The graph reaches a maximum of 200 in 2004
- Then it decreases by 25 each year
2008 is 4 years from 2004.
So, the prediction is;
Year 2008 = 200 - 4 * 25
Evaluate
Year 2008 = 100
Hence, the number of CDs the students at your high school bought in 2008 is 100

Answer:
BCG =65
Step-by-step explanation:
DCG + GCB = DCB
We know BCG = 31x+3 and GCD = 12x+2 and BCD = 91
Substituting these in
12x+2 + 31x+3 = 91
Combine like terms
43x +5 = 91
Subtract 5 from each side
43x+5-5 = 91-5
43x = 86
Divide by 43
43x/43= 86/43
x=2
BCG = 31x+3
=31(2)+3
=62+3
=65
