x = number of comics Ross bought
A = 10*x = amount spent on buying those x number of comics at $10 each
B = 17*(x-1) = amount Ross gets from selling every comic book except one
B-A = 17*(x-1)-10x = 7x-17 = profit = 49
7x-17 = 49
7x = 49+17
7x = 66
x = 66/7
x = 9.42857 approximately
Because x isn't a whole number, I'm thinking that there's a typo in the problem somewhere. I would double check with your teacher.

Answer:
The cost in 3 years is $80.19.
Step-by-step explanation:
The cost of computer component is $110 today.
The cost is decreasing at a rate of 10% per year.
When it decreases by 10% per year then it is exponential.
Initial cost is $110. When it decreases 10% per year, the decay factor is 1-0.10 =0.90.
So, we could use the exponential formula y=
Where 'a' is initial cost and b is decay factor.
Our equation would by plug in 'a' as 110 and 'b' as 0.90.
We get
Now, to find the cost in 3 years, use x as 3.
Which is simplified to
y=$80.19
5,000+400+80+4+.3+.06+.006
