Suppose you make a $5 bet on the number 0 on a roulette wheel with 38 slots labeled 00, 0, 1, 2, 3, ... , 36. If 0 is spun, you win a net gain of $175. If a 0 is not spun you lose the $5 bet. If you spin the wheel 50 times, how much money can you expect to gain or lose? Round to the nearest cent.
Do not round until the final answer.
Enter an expected loss as a negative number.
