Question

what part of the campers were young adults, teens, or children?
(a) $\frac{11}{20}$
(b) $\frac{3}{5}$
(c) $45\\%$
(d) $90\\%$

Explanation:

Step1: Find the number of campers in each group

From the bar - graph:
Number of senior citizens \(= 50\)
Number of adults \(= 60\)
Number of young adults \(= 5\)
Number of teens \(= 25\)
Number of children \(= 60\)

Step2: Calculate the total number of campers

Total number of campers \(=50 + 60+5 + 25+60=200\)

Step3: Calculate the number of young adults, teens, and children

Number of young adults, teens, and children \(=5 + 25+60 = 90\)

Step4: Calculate the fraction

The fraction of young adults, teens, and children is \(\frac{90}{200}=\frac{9}{20}\) (simplify: divide numerator and denominator by \(10\)).
Convert \(\frac{9}{20}\) to a percentage: \(\frac{9}{20}\times100\% = 45\%\)

Answer:

C. \(45\%\)
