Jamal is collecting cans to raise money for a local charity. He has already collected 40 cans. If each can he sells will give him $0.25, how much money will he have made if he sells all of the cans he has collected?

1. $10 ✓
2. $15
3. $5
4. $12.50

Why: To find out how much money Jamal will make from selling the cans, we multiply the number of cans (40) by the price per can ($0.25). So, 40 * 0.25 = $10. This means Jamal will have made $10 if he sells all of the cans he has collected.

Carlos is organizing a community clean-up event in his neighborhood. He plans to provide 5 trash bags for every 4 volunteers that sign up. If 20 volunteers sign up, how many trash bags will Carlos need to provide for the event?

1. 25 ✓
2. 20
3. 15
4. 30

Why: To find out how many trash bags Carlos needs, first determine how many groups of 4 volunteers there are in 20. Since 20 ÷ 4 = 5, there are 5 groups of 4 volunteers. Since Carlos provides 5 trash bags for each group, the total number of trash bags he needs is 5 groups × 5 bags/group = 25 bags.
