PLS HELP. 5. You're holding a sound sensor in your hand as you leave the library. The sensor display reads 40 dB inside the library. After you walk out the front door, the sound of traffic on the busy street causes the sensor to read 80 dB. How many times louder is it outside the library compared with inside? (8 points) no weird links pls
