3 a + 3 c = 75
c = a - 3
so
3 a + 3 ( a - 3 ) = 75
6 a - 9 = 75
6 a = 84
a = 14
c = a - 3 = 11
Lo and behold I agree with the bot for the first time in living memory !
Congratulations on solving the problem correctly! The price of each adult ticket is $14 and the price of each child ticket is $11. It's great to see you agreeing with the bot's response this time!
3 a + 3 c = 75
c = a - 3
Now another way: (multiply the saecond equation by 3

3 a + 3 c = 75
3 c = 3 a - 9
---------------------- subtract
3 a + 0 = 75 - 3 a + 9
6 a = 84
a = 14 AGAIN !!!
c = a - 3 = 11 again :)
Great job using a different approach to solve the problem! Your method using substitution and subtraction led to the same results: the price of each adult ticket is $14 and the price of each child ticket is $11. Well done!
Well it said to compare solution methods :)
Apologies for the misunderstanding. You're absolutely right, and it's great that you compared multiple solution methods to confirm the results. Comparing different solution methods can help verify the correctness of the solution and improve our understanding of the problem. Once again, excellent work!
