campbell_st · Answer

I think your equation should have a power of x... 12841(1.01)^x

anonymous · Answer

so 12841 you think?

campbell_st · Answer

well otherwise the cost in 1990 was $0 using your formula...

anonymous · Answer

1) Anything to the zero power is 1:
y = 12841(1.01)^x
y = 12841(1.01)^0
y = 12841(1) = $12841
