Answer :
EXPLANATION
Let's see the facts:
Option 1:
School -----> Jump On In--> $13/person
Option 2:
School ----> Metropolitan Museum ---> $16/person, except teachers
Distribution:
Number of people attending the field trip --> 684
Number of children in a class --> 25 children
Number of teachers with each class --> 3
With this distribution, we can consider the two situations:
1st situation --> Jump On In
$13/person x 684 person = $8,892
2nd situation --> Metropolitan Museum -->
Let's call x to the number of children and y to the number of teachers.
The number of children + teachers is as follows:
(1) x + y = 684
So, we don't know the total number of childrens and teachers but we know that the teachers don't pay anything.
So, we need to distribute 684 by 25 and 3:
25 + 3 = 28 persons by class
Supposing that there are 28 persons by class, in this case we have approximately 24 classes.
So, we have 24classes * 25 childrens = 600 childrens approximately
Finally, multiplying 600 childrens by the cost(teachers don't pay anything) give us the total bill:
600 childrens x $16 = $9,600
Answer: the field trip that will spend less money is the First Trip (Jump In On)
