Philip

Philip is snorkeling along a coral reef. He's wearing an altimeter, which tracks his elevation. Philip snaps a picture of the reef at an elevation of -10 1/2 feet. Then he spots a nurse shark and swims to it for a closer look. By the time he reaches the shark, his elevation changes by -3 1/2 feet. What is Philip's elevation when he reaches the shark?

Correct answer:

x =  -14 ft

Step-by-step explanation:

a=1021=221=10.5 ft b=321=27=3.5 ft  x=a+b=221+27=221+(7)=228=14 ft
