Perception refers to the set of processes we use to make sense of the different stimuli we're presented with. Our perceptions are based on how we interpret different sensations. The perceptual process begins with receiving stimuli from the environment and ends with our interpretation of those stimuli.

Organizational Behavior - Perception. Perception is an intellectual process of transforming sensory stimuli to meaningful information. It is the process of interpreting something that we see or hear in our mind and use it later to judge and give a verdict on a situation, person, group etc.

Cindy collects 20 insects for her biology class, all of which are spiders, dragonflies, and cicadas. (Note that a spider has 8 l
Ronch [10]

Cindy collects 4 cicadas in total.

Let,

D represent the number of dragonflies

C represent the number of cicadas

S represent the number of spiders

Since the total number of insects is 20:

Equation 1

D+C+S=20

A spider has 8 legs, a dragonfly has 6 legs, and a cicada has 6 legs. Since the total number of legs is 138:

Equation 2

6D+6C+8S=138

A spider has 0 wings, a dragonfly has 4 wings, and a cicada has 2 wings. Since the total number of wings is 36:

Equation 3

4D+2C+0S=36

Multiplying equation 1 with 6 and subtracting it from equation 2:

6D+6C+8S-6(D+C+S)=138-6(20)

2S=18

S=9

Multiplying equation 1 with 4 and subtracting it from equation 3:

4D+2C+0S-4(D+C+S)=36-4(20)

-2C-4S=-44

Substituting S with 9:

-2C-4(9)=-44

-2C=-8

C=4

Thus, Cindy collects 4 cicadas in total.
