Answer:21 students.i hope it helped
So in this problem we can see that there will be 60 people at the party. Following the conditions for this event that state the following: $750 for up to 30 people and every extra person pays $20. To show that the cost will be $1350 in total we simply do this:
For 30 people we have $750 dollars. Now every other person after pays only $20. That means that another the other 30 people will pay in total only $600.
If we add them we get: $750 + $600 = 1350. This shows that the cost will be $1350.
I hope it helps, Regards.
