Answer:

The alarm bell will ring at 473 psi.

Step-by-step explanation:

To answer this, find 215% of 220 pounds per square inch:

Convert the percentage 215% to its decimal fraction equivalent, 2.15, and then multiply 220 pounds per square inch by it:

2.15(220 psi) = 473 psi

The alarm bell will ring at 473 psi.
