We also know that he bought three times more potatoes than shrimps, therefore:
Using the second equation on the first one, we have:
He bough 1.25 lbs of shrimp and 3.75 lbs of potato.
The equation to find the air pressure (P(h)) at a height above sea level (h) is given by
Where,
- P(h) is the new pressure at height h
is the air pressure at sea level, and
- h is the height (measured in meters).
We want to know the new pressure that is 65% of . So we should substitute
in P(h) (new pressure) to get the equation:
. Answer choice B is the correct one.
