Answer:
x = 1/3(500 + 5y)
Step-by-step explanation:
Given that:
x child tickets for $3
y adult tickets for $5
3x + 5y = 500
To solve for x
3x = 500 + 5y
Divide through by 3
3x /3 = 500/3 + 5y/3
x = 1/3(500) + 1/3(5y)
x = 1/3(500 + 5y)
2.)
If the total number of tickets sold was made available, then a more direct solution would have been obtainable as we can have two different equations;
One for the total number of ticket sales and the other of the total revenue from ticket sales.
