Answer: $603.75 per week
Explanation: 11.50 / 60 minutes = 0.19166666666
0.19166666666 x 450 minutes = 86.249999997
86.249999997 x 7 days = 603.749999979
If you round 603.749999979 to the nearest hundredth, you
get 603.75.
Therefore, Amanda made $603.75 that week.

Answer:
-7
Step-by-step explanation:
8x - 2 = 7x - 9
8x - 2 - 7x = 7x - 9 - 7x
x - 2 = -9
x - 2 + 2 = -9 + 2
x = -7
3pm to 7pm is 4 hours. 4 hours times 2 degrees dropped every hour is 8 degrees total dropped within those 4 hours. The previous temperature of 4 degrees at 3pm minus the 8 degres dropped is -4.
