Answer:
2.2 gallons per minute
Step-by-step explanation:
The rate of change is 2.2 gallons of water every minute
The formula is pi*r^2*h/3
your answer would have to be B
table A from 2-3 minutes it rose 64.9-61.3 = 3.6
from 3-7 it rose 79.3 -64.9 = 14.4 = 3.6 degrees per minute
Table B needs to raise faster than 3.6 per minute
64.4 -61 = 3.4
64.6 - 61 = 3.6
64.3 -60.6 = 3.7
so the 3rd table is correct
100%-20%= 80%=0.8
115(0.8)= 92
92(1.075)= 98.9
The final price of the coffee table is $98.90.
Hope this helps!
