Please Help! Algebra 2

You purchased a baseball card for $8 when you were 10 years old. The value of the card increased by 5% each year. Write an exponential model that gives the value y (in dollars) of the card T years after you purchased it.

This is what I put

y= 8(1 + .05) ^T

your so helpful! okay i have another one I promise I'm almost done! :) 

Expand the logarithm 

log6 2x/y

agent0smith · Answer

Use this first 
log(A/B) = logA - logB

Then you can use 
log(CD) = logC + logD
