Q: Megan is delivering meals on wheels. Out of her 30 clients, 7 need vegan meals, 8 need kosher meals, and three people need meals that are both vegan and kosher. How many meals does Megan deliver that are neither kosher nor vegan?
A: First, add the number of kosher meals to the number of vegan meals: 7 meals + 8 meals = 15 meals. Then subtract the three meals that are both kosher and vegan since they got counted twice: 15 meals - 3 meals = 12 meals. Finally, subtract that number from the total number of meals to find the number of meals that are neither kosher nor vegan: 30 meals - 12 meals = 18 meals. The answer is 18.

On Monday Kendra saw 5 sites x 7 birds / site = 35 different birds. On Tuesday Kendra saw 5 sites x 5 birds / site = 25 different birds. On Wednesday Kendra saw 10 sites x 8 birds / site = 80 different birds. In total Kendra saw 35 birds + 25 birds + 80 birds = 140 different birds. In total Kendra visited 5 sites + 5 sites + 10 sites = 20 sites. On average Kendra saw 140 birds / 20 sites = 7 different birds at each site. The answer is 7.
