Bobby saw 2 Lions at the zoo. He saw 4 times as many elephants as the Lions. He also saw half as many giraffes as elephant. How many animals did he see in all?

Bobby saw 11 animals in total

Step-by-step explanation:

we will represent the relationships that give us

L = Lions

E = Elefaphants

G = Giraffes

A = Animals

L = 2

E = 4 * L

G = 1/2 * L

A = L + E + G

in the second and third equations we replace L with its value (2)

E = 4 * L

E = 4 * 2

E = 8

G = 1/2 * L

G = 1/2 * 2

G = 1

now in the last equation we replace the values of L, E and G

A = L + E + G

A = 2 + 8 + 1

A = 11
