Answer:
The squid exhibit is 2 units north of the giant octopus
Explanation:
see the attached figure to better understand the problem
we know that
1) The aquarium entrance is located in the lower left corner of the map
Let
A(0,0) ---> the coordinates of the aquarium entrance in the map
2) From the dot labeled“aquarium entrance”, Dashiell walked 4 units to the right and then 2 units up to get to the giant octopus
Let
B ---> the coordinates of the giant octopus in the map
The x-coordinate of B is equal to 0+4=4 units
The y-coordinate of B is equal to 0+2=2 units
so
Point B(4,2)
3) From the dot labeled “giant octopus”, Dashiell walked 2 units to the left to get to the penguins
Let
C ---> the coordinates of the penguins in the map
The x-coordinate of C is equal to 4-2=2 units
The y-coordinate of C is equal to 2+0=2 units
so
Point C(2,2)
4) From the dot labeled “penguins”, Dashiell walked 2 units up and then 1 unit to the left to get to the sharks
Let
D ---> the coordinates of the sharks in the map
The x-coordinate of D is equal to 2-1=1 units
The y-coordinate of D is equal to 2+2=4 units
so
Point D(1,4)
5) The squid exhibit is located three units east of the Sharks
Let
E ---> the coordinates of the squid exhibit in the map
The x-coordinate of E is equal to 1+3=4 units
The y-coordinate of E is equal to 4+0=4 units
so
Point E(4,4)
we have that
the giant octopus is located at B(4,2)
the squid exhibit is located at E(4,4)
To find out how many units north of the giant octopus is the squid exhibit, subtract the y-coordinate of the giant octopus from the y-coordinate of the squid exhibit
(4-2)=2 units
therefore
The squid exhibit is 2 units north of the giant octopus
