Solve this x = 14.5
y = 800(.95)^x
y = 50(1.15)^x

Is that x the given value or is that answer?

anonymous · Answer

given value :)

anonymous · Answer

So we need to solve for y in both functions?

anonymous · Answer

no seperate. there should be two different answers

anonymous · Answer

Yeah that is what I meant

anonymous · Answer

sorry, i should've said that >.<

anonymous · Answer

Lets start with the first one.
y=800(0.95)^14.5
I got this by plugging in 14.5 for x, 
now by order of operations we need to do the exponent first so use your calculator to find (0.95)^14.5

anonymous · Answer

actually don't have a calculator lmao, but the one on google told me it was 0.475

anonymous · Answer

thats fine, now we have y=800(0.475) what is 800*0.475?

anonymous · Answer

380?

anonymous · Answer

Yes so in the first one Y=380

anonymous · Answer

ok great ^.^

anonymous · Answer

Do you think you can do the second one by yourself? Or do you need me to show you how to do that one too.. it is identical to the last one

anonymous · Answer

i think i'm good from here, thanks!

anonymous · Answer

no problem :)
