Question: Katy participated in a summer reading program at her local library. She read 8 books in June, twice as many in July and three fewer in August than she did in July. How many books did Katy read during the summer? Think carefully first, then make a decision:
Katy read twice as many books in July as she did in June, so she read 2 * 8 = 16 books in July. She read three fewer books in August than she did in July, so she read 16 - 3 = 13 books in August. So, including June, she read 8 + 16 + 13 = 37 books total. So the answer is 37.
