At the end of each year, the population is 1.0825 times what it was at the beginning. At the end of 6 years, it will be .. 330,000 * 1.0825^6 ≈ 530,984
Let x represent the worth of the professional basketball player's autograph a year ago. Since his autograph's worth increased by 40% now, $364 is 1.40x.
364 = 1.40x
Solving for x gives x = 260.
Thus, the autograph of the basketball player was worth only $260 last year.
