Question

Betty wants to participate in a dance recital. She cannot miss more than 20% of the 50 classes before the recital. What is the minimum numbers of classes Betty must attend in order to be in the recital?

a-7
b-8
c-9
d-10

Answer 1

10 classes

the answer is D 10

Explanation:

Given data

number of classes= 50

percentage = 20%

We want to calculate 20% of 50

=(20/100)*50

=0.2*50

=10

This means that she cannot miss more than 10 classes

therefore she cannot miss 10 classes
