Answer:
120
Step-by-step explanation:
Any of the 5 teams can finish first. For each of those, any of the 4 remaining teams can finish 2nd. For any of those 5·4 = 20 permutations, any of the 3 remaining teams can finish 3rd. The counting continues in like fashion, so the total number of possible finish sequences is ...
5·4·3·2·1 = 5! = 120 . . . . ways they can finish
If you do cross multiplication and multiply 90 by 2 then divide that answer with 30, your answer should be 6
Answer:
Step-by-step explanation: 1,250+1,100=2,350.
