Step-by-step explanation:
The information that we kow about the shape of the aquarium:
length:

width:

when the reef is submerged, the water level rises 3 feet. The volume that those 3 ft represent in the aquarium will be the volume of the reef.
Thus, we calculate the volume of water "addition" with the same length and width as the aquarium but with a deep of 3 feet (thi is because the reef caused the water to rise 3 feet), and this is the volume of the reef that was added to the aquarium:

The volume of the stone is 
Answer: 67
Step-by-step explanation:
Let x = number of passengers.
Case M: x< =75 (no refund)
Cost per passenger = $230
To generate the revenue, we should satisfy
230x =15990
x = 69.5
Set x = 67 in order to generate the revenue.
Case N: x>75
Cost per passenger minus refund = 230 - 5 = $225
Therefore
225x = 15990
x = 71.1
Because x<75, ignore this answer.
More than 75 passengers will generate more than $15990.
Are there numbers?
If there are numbers add b and c then add d to the a then divide a with the b and c and you get the answer if that even makes sense
