Answer:
Explanation:
Let r be the cost of one ride ticket, and let d be the cost of one drink ticket.
Then we can write the following system of equations to represent the situation:
For Carlos:
6r + 3d = 21.75
For Juan:
10r + 6d = 39.50
In the first equation, 6r represents the cost of 6 ride tickets and 3d represents the cost of 3 drink tickets that Carlos bought. Together they add up to $21.75, the total amount Carlos spent.
In the second equation, 10r represents the cost of 10 ride tickets and 6d represents the cost of 6 drink tickets that Juan bought. Together they add up to $39.50, the total amount Juan spent.
