Hello from MrBillDoesMath!
Answer:
Choice B, 24 adults
Discussion:
From the attachment we see that 4 buses are full (they hold 4 * 40 = 160 passengers as each bus can hold 40 people) and the 5th or last bus was 4/5 full. That means the 5th bus had 4/5(40) = 160/5 = 32 passengers. So the total number of passengers on all buses is
(4 * 40) + 32 = 192
Since 1/8 of all passengers are adults, (1/8) 192, or 24, passengers are adults. This is Choice B
Thank you,
MrB
