an exploring ship is pulling up a diver at the rate of 25 feet per minute. The diver is currently 100 feet below the sea level. How deep was the diver 15 minutes ago?

equation: 25x+100
and x=minutes
so 25 minutes multiplied by 15 is 375 and he’s 100 below right now so 375+100=475 therefore he was 475ft. below sea level
