Question: Lana had 8 blank pages left in her binder, but she knew she would need more for her next class. Duane took half of the 42 pages in his binder out and gave them to her. How many pages does Lana have in her binder after adding Duane’s? Think carefully first, then make a decision:
Duane gave Lana 42 / 2 = 21 pages. After adding Duane’s, Lana has 21 + 8 = 29 pages in her binder. So the answer is 29.
