Rachel fills 13 water bottles per hour, so she contributes 13R. Alyssa fills 15 bottles an hour, so she contributes 15A, plus 5 for the additional water bottles filled. Thus, the full expression is:
13R+15A+5

You're very close. However, the less steep line should go through (4,7) and not some point slightly above that location. Also, the shaded region should be above both dashed lines at the same time.

Answer:
28
Step-by-step explanation:
First find 25% of 21.5. You can do this by multiplying .25 by 21.5. That gives you 5.375. Subtract that from 21.5. That gives you 16.125. Money only has two decimal places so round 16.125 up to 16.13 and that's your answer! <3
