Exercise Answers
- B The average salary for mathematics and engineering majors is ≈$51,000,
and the average salary for humanities and arts majors is ≈$34,000. The percent
greater formula is % of – 100% = % GREATER. Plug in the values to get the
salary of mathematics and engineering students as a percentage of the salary
of humanities and arts students: $51,000/$34,000 = 150%. Subtract 100%. The
answer is 50%. - B The approximate number of students concentrating in the social sciences
was 23% × 4,792 ≈ 1,102. 10% of 1,102 is approximately 110. - E The total salary for graduates of the humanities and arts = average ×
number of students. The average is approximately $34,000. The number of
students is approximately 0.19(4,792) ≈ 910. The total salary for these students
is approximately $34,000(910). The total salary for graduates of the natural
sciences = average × number of students. The average is approximately
$53,000. The number of students is approximately 0.32(4,792) ≈ 1,533. The total
salary for these students is approximately $53,000(1,533). The average salary
for both concentrations combined equals:
