Final answer:
The two equations are x + y = 7 and 4x + 9y = 43, which represent the total number of tickets and the total cost, respectively.
Step-by-step explanation:
To determine how many of each type of ticket Mr. Jackson bought, we need to write a system of equations. Let x represent the number of child tickets and y represent the number of adult tickets. There are two conditions that we know:
- Mr. Jackson bought a total of 7 tickets.
- Mr. Jackson spent a total of $43 on tickets.
The first condition can be written as an equation:
x + y = 7 (the total number of tickets).
The second condition involves the cost of the tickets. Child tickets cost $4 each and adult tickets cost $9 each.
Therefore, the second equation is:
4x + 9y = 43 (the total cost of tickets).
Together, these two equations form the system:
