4 Which equation will solve the following word problem? Sue's class has 50 students. 20% of the students are in art class. How many students are NOT in art class?

50/(50 * 0.20) = x

50 + (50 * 0.20) = x

50 - (50/0.20) = x

50 - (50 * 0.20) = x

50 - (50 * 0.20) = x

Step-by-step explanation:

Student in art class = 20% or 20/100 or 0.2

Student NOT in art class = 80% or 80/100 or 0.8

Total number of students = 100% or 100/100 or 1, which equivalent to 50 students

x = total number of students - 20%

= 50 - ( 50 x 0.2 )

= 50 - 10

= 40 students
