Number 3 looks good! Only I would put the negative before the dollar sign.
In #4, the number line needs to look like the one i attached.
Next, to explain, the distance between -5 1/2 and 4 2/3 is in the second picture. The answer is the water level rose 10 1/6 feet.
To start, a loss makes the player lose 3 points, so in "points earned" all the losses need to have a point value because technically they are gaining -3 points.
To get the total, you just need to add all the points together.
2.2 + 0.25 =4.45 (I changed the fraction 1/4 to a decimal to make it all in one format)
4.45+2.2=6.65
6.65+2.2=8.85
8.85+0.25=9.1
9.1+-3=6.1 (Its a +-3 because you are adding a negative, but just treat it as a normal subtraction)
If you have any questions, please ask!
