Question

Nine buses hold 85 people each. If 693 people buy tickets for a trip, how many seats won’t be taken?

Answer 1

72

Explanation:

you take 85 * 9

85 = # of seats

9 = # of buses

then you get 765

next, you take 765 - 693

765 = # of seats

693 = # people who bought tickets for a trip

finally you get 72

72 = # of empty seats
