Question 813859: The cost of a certain brand of camera has been increasing at 8% per year. If a camera now costs $150, find the cost in two 2 years and 6 months from now.
I can do the computations; I just can't figure out a formula.

You can put this solution on YOUR website!
"increasing at 8% per year", exponential growth.
You really mean price or not?
P=150%2A%281.08%29%5Ex, x=years of price growth.

2 years and 6 months may be 2.5 years.
P=150%2A1.08%5E2.5 and you might use a scientific calculator.
P=181.82
