Answer:
It approximately dropped 0.027777 per hour.
Step-by-step explanation:
First, we calculate the decrease.
Decrease = 11/40 = 0.275
Then, we calculate the time interval.
From 10 pm to 7:54 hours will be 9.54 hours
Time interval= (9 + 54/60) hours
Time interval=9.9 hours
Finally, we calculate how much it dropped each hour
0.275/9.9 ≈ 0.027777
So it approximately dropped 0.027777 per hour.
Answer:
1100
Step-by-step explanation:
price = 1500
discount= 15%
15% of 1500 = (15/100)*1500= 15*15= 225
so selling price = 1275
profit is selling price - cost price
1275 - CP = 175
CP = 1275-175= 1100
