But heureka answered correctly.
My answer: = z
\(3^{x+1}=2^{x+2}\\ (x+1)\ln 3=(x+2)\ln2\\ x\ln 3 - x\ln 2 = 2\ln 2 - \ln 3\\ x = \dfrac{2\ln 2 - \ln 3}{\ln 3 - \ln 2}\)
Use the calculator and you get the answer.
Thank you :)
I never have learnt how to do that!! That method is awesome!!
Omi: A mistake in the second step: ln e^2t = ln 200 <--- 2t should be changed to 3t. A typo.
2e^(3t) = 400
e^(3t) = 200
3t = ln 200
t = (ln 200)/3
Oh my god!! I have to escape from that!! I can't get caught!!
Total = $12.83, Cinnamon Bun = $3.42 and Giant candy cane = $5.76.
The subtotal amount used on cinnamon bun and giant candy cane = $3.42 + $5.76 = $9.18
Then use 12.83 - 9.18 and you get an answer of $3.65
