Consider the provided information.
The Initial value of poster = $ 18
After 1 year amount of increase = $ 20.70
With the rate of 15% = 0.15

.
The digit '1', the first copy of '1', is in the ten thousands place. To the right of this digit is 3. Since 3 is not 5 or larger, we simply change everything after the '1' to zeros
So we go from 413,125 to 410,000
The final answer is 410,000
