Answer:
Step-by-step explanation:
Let
x = cost for one adult
y = cost for one child
z = cost for one senior.
<u>The Reid family:</u>
take 2 adults and 2 children and paid 
that is 
, so
<u>The Mghee family:</u>
take 1 senior, 2 adults and 1 child and paid 
that is 
, so
<u>The Griffiths family:</u>
take 1 senior and 3 adults and paid 
that is 
, so
You get the system of three equations:
From the first equation:
From the third equation:
Substitute them into the second equation:
Then
Hence,
the cost for one adult is 
the cost for one child is 
the cost for one senior is 
<u>The Linton family</u> takes 1 senior, 2 adults and 3 children and paid
Alright! Given that C(x) is Cost(Students) = 558, we can eliminate:
2. 558 students paid to attend the event.
5. The event generated $124 from student revenue.
Now, in order to find the cost per student we simply divide 124 on both sides:
124 cancels on the left and 558/124 is 4.5 or $4.50.
Since we just determined the cost of one student, we can eliminate 3.
To check if 124 students paid, we simply add the cost to the equation and check:
4.5(124) = 558
558 = 558 √
It checks out, so we determined that both 1 and 4 are correct.
