Question 1:
Multiply 24 by 9 to find the amount of people carried in one day.
24 × 9 = 216
Now multiply that by 30 to find the amount of people carried in a month.
216 × 30 = 6,480
Option B: 6,000 passengers is correct because 6,480 is closer to 6,000 than 10,000.
Question 2:
Multiply 12 by 12 to find a gross.
12 × 12 = 144
Now to find 12 gross, multiply 144 by 12.
144 × 12 = 1,728
Option C: 1,728 items is correct.
