A 1970 comic book has appreciated 10% per year and originally sold for $0.35. What will it be worth in 2010?

60 I think?

I may be wrong-

Answer:

15/11

Step-by-step explanation:

Use pythagorean theorum: c^2 = a^2 + b^2, where BC = c, AB = a, AC = b
so b^2 = c^2 - a^2 --> b = SR(c^2 - a^2), where SR means square root of ( )
b = SR(64 - 49) = SR(15) = 3.873 = B) 3.87 units

The answer would be C

S= 70w + 750
s(19) = 70w x 19+350= 1680 
so its 1680
