Three consecutive even numbers have a sum between 84 and 96.
a. Write an inequality to find the three numbers. Let n represent the smallest even number.
b. Solve the inequality.

a. 84 < n + (n + 2) + (n + 4) < 96
b. 26 < n < 30

a. 84 ≤ n + (n + 2) + (n + 4) ≤ 96
b. 78 ≤ n ≤ 90

a. 84 < n + (n + 1) + (n + 2) < 96
b. 27 < n < 31

a. n + (n + 2) + (n + 4) < –84 or n + (n + 2) + (n + 4) > 96
b. n < –30 or n > 31
