Answer:
Step-by-step explanation:
x and y are defined as the numbers of adult's tickets and the number of children's tickets, respectively. So x=30 means 30 adult tickets; y=7 means 7 children's tickets.
Revenue from sales of those numbers of tickets would be $275.
Answer:
30 adult's tickets were sold and 7 children's ticket were sold.
Step-by-step explanation:
We are given the following information in the question:
Cost of Adult's tickets = $8
Cost of Children's ticket = $5
Total money collected = $275
Let x be the number of adult's tickets sold and y be the number of children's ticket sold.
Then, we can write this in the form of equation:
[tex]8x + 5y =275[/tex]
The point (30,7) means that 30 adults ticket were sold and 7 children's ticket were sold.
Putting these value in the equation:
[tex]8x + 5y =275\\8\times 30 + 5\times 7 =240 + 35 = 275[/tex]
which is true.
Thus, 30 adult's tickets were sold and 7 children's ticket were sold.
