the pressure on a scuba diver at sea level is 14.7 pounds per square inch (psi). the pressure increases 0.445 psi for each foot of depth. suppose the pressure on a diver is 32.5 psi. how deep is he?
ms.kork sold her car for $8700. this was $100 more than two fifths of what she had paid for the car originally. how much had ms.kork paid for the car?

1. if at sea level it is 14.7psi you first have 32.5psi-14.7psi =17.8psi to get the change in pressure
ther you take 17.8psi/.445 psi per foot to get how deep the diver is(in feet)
so the answere is 40 ft
2. from the info, 8700. is 100 more than 2/5 of what she paid
so, ((2/5)x)+100=8700 where x= what she paid
so x=(8700-100)/(2/5)=$21500
