Answer:
Rahm: 0.8
Bain: 1.2
Step-by-step explanation:
For this, they ask for the rate of change or slope. To find slope you can use slope formula to get your slope/rate of change.
Steps for Rahm:
We can take points (10,8) and (20,16) and find the slope with the following formula: 

This is the rate of change for Rahm
Steps for Bain:
Take the points (5,6) and (11,13.2) and plug them into the Slope Formula:

Therefore, Bain hiked faster than Rahm for he had the higher rate of change compared to Rahm.
Answer:
8x + 3
Step-by-step explanation:
The cost of 5 t-shirts and 3 skirts
= 5(x - 3) + 3(x + 6)
