Answer 1

$33

Explanation:

A professional gambler reported that at the end of the first race at the track he had doubled his money. He bet $33 on the second race and tripled the money he came with. He bet $60 on the third race and quadrupled his original bankroll. He bet $68 on the fourth race and lost it, but still had $64 left. With how much money did he start?

Let us represent, the amount of money he had at the start= x

Money after the first race=2x

Money he had after betting=2x-33

Money after the second race=3x

Money he had after betting on the third race=3x-60

Money after the race=4x

Money he had after betting on the fourth race=4x-68

Money after the race=$64

4x-68=64

4x=68+ 64

4x = 132

x=132/4

x = 33

Therefore, he had $33 at the start
