Calculate the income due each year and then summarize it.

First year10000 * (1+0.08)10

……

Tenth year,10000 * (1+0.08) ...1.

This is a geometric series, using the summation formula of equal ratio series.

Or use the formula directly.

Xn=a[ 1-( 1+b)^n]/-b

Where x represents the total amount (including income and principal) in ***n years.

A means the amount invested each year (10000 yuan).

B stands for income (for example, the annual income is 8%, and its b = 0.08), and n stands for n power.
