Let's estimate how much approximately can be bought for $690. $690/ 1.25 = 552 trees. in 552 there are 5 hundreds. For each hundred you receive $5, hence 5*$5 = $25. Denote the number of trees as n. Thus $1.25 * n& - $25 =$690 n = (690 + 25)/1.25 = 572. In 572 there are still 5 hundreds, so the answer 572 is correct.
