Angie decided to use her class as a sample to predict the total number of students in her school wearing red on Valentine’s Day. She counted 11 students wearing red in her class of 24 students. Using this ratio, how many of the 480 students in her school will she estimate are wearing red?

\(ratio_1= 11:24\)

\(class={school\over 20}\)

\(school = {class[20]}\)

\(ratio_1 = 220:480\)

 

Total:

\(220\)
