Answer:
Step-by-step explanation:
The cost for 78 students is $279.
If s is the number of students and you have 78 students attending, do 3*78 first. You should get 234, then once you get that total, don't forget to add 45 dollars onto it.
I think it’s the first one. 30:54 because 5 times 6 is 30 and 9 times 6 is 54.
