Monika dove 9 meters below the ocean's surface. She then dove 13 meters deeper. Then she rose 19 and one-fourth meters. What was her position concerning the water's surface (the water surface = 0, minus values = above water level, plus = above water level)?

Correct answer:

x =  -11/4 m

Step-by-step explanation:

a=9 m b=13 m c=1941=19+41=419 4+1=476+1=477=19.25 m  x=a+b+c=(9)+(13)+477=411 m=243 m=2.75 m
