Question

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

Answer 1

Is that x the given value or is that answer?

Answer 2

given value :)

Answer 3

So we need to solve for y in both functions?

Answer 4

no seperate. there should be two different answers

Answer 5

Yeah that is what I meant

Answer 6

sorry, i should've said that >.<

Answer 7

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

Answer 8

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

Answer 9

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

Answer 10

380?

Answer 11

Yes so in the first one Y=380

Answer 12

ok great ^.^

Answer 13

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

Answer 14

i think i'm good from here, thanks!

Answer 15

no problem :)
