Solution by Steps

step 1

Calculate the total number of people who chose the colors represented on Chelsea's graph

step 2

Add the number of people who favored each color: Blue (80), Green (over 120), Red (60), Yellow (100), Pink (100)

step 3

Since Green exceeds 120, use the minimum possible number which is 121 to ensure we don't overestimate

step 4

Perform the addition: $80 + 121 + 60 + 100 + 100 = 461$

step 5

Subtract the total from step 4 from the total number of people surveyed (500) to find the number of people who chose other colors

step 6

Perform the subtraction: $500 - 461 = 39$

[1] Answer

39 people

Key Concept

Subtraction to find the remainder

Explanation

To find the number of people who chose colors not represented on the graph, subtract the sum of the people who chose the colors on the graph from the total number of people surveyed.
