Answer:
A. The first choice.
Step-by-step explanation:
Look at function 1.
Month 1 -----> $50
Month 2 ----> $40
The difference between month 2 and moin th 1 is 1 month.
The difference between $40 and $50 is -$10. In other words, in function 1, the amount, y, went down $10 in a month. The rate of change of function 1 is -$10/month.
Function 2
y = -9x + 60
The rate of change is the slope. The slope of function 2 is -9. In function 2, the amount of money changes -$9/per month.

Answer:
7:30 , 7:55 ,8:20 ,8:45 ,9:00, 9:25
Step-by-step explanation:
We subtract 7:55 from 8:20
1) 8:20
- 7:55
2) 7:2 60
-7:55
3) 0:25
we put 60(because it's time and we put in in 1 hour 60 minutes)and we take 1 hour from the 8 to put the 60 minutes ,so we continue adding 25 minutes to the time.
