Answer:
Lose $0.05
Step-by-step explanation:
There are 38 possible spots on the roulette wheel (numbers 1 to 36, 0 and 00).
If the player can choose four numbers on single $1 bet, his chances of winning (W) and losing (L) are as follows:

The expected value of the bet is given by the probability of winning multiplied by the payout ($8), minus the probability of losing multiplied by the bet cost ($1)

On each bet, the player is expected to lose 5 cents ($0.05).
Subtract it like you would and then add - so it would be -16

2 | ($25 x 2) = $50 | ($11 x 2 + 18) = $40 | Profit = $50 - $40 = +$10
| ---- | -------- | -------
3 | ($25 x 3) = $75 | ($11 x 3 = 18) = $51 | Profit = $75 - $51 = +$24
| ---- | --------- | -------
Total Number of toys = 1+2+3 = 6
Total Earnings = $25+$50+$75 = $150
Total Cost = $29+$40+$51 = $120
Total Profit = $150-$120 = +$30
