1/3 * 84 = 28 were under 25
2/7 * 84 = 24 were at least 50
28 + 24 = 52
84-52 = 32 were between 25 and 50
Answer:
32 candidates are between 25 and 50.
Step-by-step explanation:
84 people applied for the job. [tex]\frac{1}{3}[/tex] of the candidates for a job were 25 years old or younger.
[tex]\frac{1}{3}[/tex] of 84 candidates = [tex]\frac{1}{3}[/tex] × 84 = 28 candidates
[tex]\frac{2}{7}[/tex] of the candidates were at least 50 years old.
[tex]\frac{2}{7}[/tex] of 84 candidates = [tex]\frac{2}{7}[/tex] × 84 = 24 candidates
age 25 and below + age 50 above = 28 + 24 = 52 candidates
Candidates between 25 and 50 = 84 - 52 = 32 candidates
32 candidates are between 25 and 50.
