To determine the difference in pressure required to raise the fire hose pressure from 50 psi to 75 psi, you subtract the initial pressure from the desired pressure.

In this case, you take 75 psi (the desired pressure) and subtract 50 psi (the initial pressure):

75 psi - 50 psi = 25 psi.

Thus, the difference in pressure required is 25 psi, which corresponds exactly to the correct answer. This calculation is straightforward, as it directly compares the two pressure levels to find out how much pressure needs to be added in order to achieve the necessary increase.
