First, we plug in the numbers. 
$40 = P(4%)(2)
4% = 0.04
40 = P * 0.04 * 2
Divide each side by 2
20 = P * 0.04
Divide by 0.04
P = 500
Lets check it! 
500 * 0.04 * 2 = 40
500 * 0.04 = 20
20 * 2 = 40
40 = 40 
 
        
                    
             
        
        
        
Answer: The sensor will read 300 liters after 5 minutes.
The sensor sensor should have read 120 liters at time -7 minutes.
Step-by-step explanation:
Given: The amount of water detected by sensor initially= 225 litres
Since, the hose fills the aquarium at a constant rate of 15 liters per minute.
Let x be the time , and y be reading of sensor then

Therefore, the sensor reads after 5 minutes (put x=5 in the equation)= 
To find the sensor read at time -7 minutes put x=-7 in the equation, we get

Hence, the sensor should have read 120 liters at time -7 minutes.
