3. Gavin needs to read at least 150 pages of his book this week. He has already read 82 pages. How many
more pages p must Gavin read this week? Write and solve an inequality.
82 + p ≥ 150; p ≥ 68
p + 82 ≤ 150; p ≤ 68
p – 72 ≥ 150; p ≥ 222
p − 82 ≤ 150; p ≤ 222
Solve the inequality for questions 4–7.
