"If the public service commission grants this increase, it will mean that between 1970 and 1987, the electric rates will have increased by more than 478 percent. That's an average rise of over 27 percent a year!" Is this correct? If not, what annual percent increase of 17 years leads to a total increase of 478 percent?

Best ResponseYou've already chosen the best response.0sorry about the duplicates. I realize that 478/17= 28.1, but she said an average of 27 percent per year

Best ResponseYou've already chosen the best response.0OK. So, that is not true. Then, say 28.1 annual leads to 478% over 17 years.

Best ResponseYou've already chosen the best response.0its just weird, because that doesnt fit the rest of the problems at all. I'm working with exponential growth/decay with equations like \[y=e ^{kt}\]

Best ResponseYou've already chosen the best response.0Oh yeah. In that case, you need to look at the compounding of the growth (increase). (1+r)^17 = 4.78 r = ?

Best ResponseYou've already chosen the best response.0x= .0877  so a rate of 8.7 percent, meaning she was wrong. I think that's it?

Best ResponseYou've already chosen the best response.0Do I need to plug that rate into something else?
