A guppy was swimming 8 feet below the surface of the river. It swam down 6 more feet to escape a large, hungry fish. What is the position of the guppy now relative to the
surface?
To solve the problem, Jenna subtracted 8 - 6 and came up with an answer of 2 feet. Is Jenna
correct? Why or why not?
Yes, Jenna is correct.
No. The answer should have been -2 feet, not 2 feet, because the guppy is
below the surface.
No. Jenna should have subtracted -8 - 6 because the guppy started 8 feet
below the surface and swam down 6 more feet.
