Answer:

1. 88 - b

Since there is 88 birds and a few of them flew away. You know b represents the amount of birds present.

2. 73 + d

Since he is earning d (amount of dollars) so what you have to do is add the amount of dollars, d, to the orginial amount, which is 73.

3. 23 x g

Since Kurt has 23 miles. If he drives 23 miles to a gallon and we have g gallons then we would multiply to find how far he can drive.
