Answer:
5 cents
Step-by-step explanation:
So the roulette wheel would have a total of 38 numbers, which means 38 different possible cases. Since you are allowed to bet on 5 numbers, the chance to win this is 5 out of 38 and to lose this is 33 out of 38.
If you win, you get 1 + 6 = 7 dollar, and if you lose, you lose 1 dollar.
Therefore the expected amount out of this game is:

or 5 cents
Original price=125
discount=x dollars or percent I will find both
sale price=81.25
so origonal-discount=sale
125-x=81.25
subtract 125 from both sides
-x=-43.75
multiply -1
x=43.75
the discount was 43.75
to convert into fraction divide 43.75 by 125 then multiply by 100
43.75/125=0.35
0.35 times 100=35%
35% discount
the equation is, y=2/3x+8/3
