We have to multiply 54 * 23, and check where the mistake is.
We start by multiplying 54 by 3, and it gives us 162
Then, we multiply 54 by 20, and it gives us 1080.
Then, we have to add these two results:
The mistake is where 6 is added to 8. It does not give 13, but 14.
The 1 of the 10 goes adding above the 1 in 162.
The result is 1,242.
Answer:the price of one child ticket is $8
the price of one adult ticket is $12
Step-by-step explanation:
Let x represent the price of one child ticket.
Let y represent the price of one adult ticket.
First tour is 4 child tickets and 8 adult tickets for 128 dollars. This means that
4x + 8y = 128 - - - - - - - - - - 1
Second tour is 6 adult tickets for 72 dollars. This means that
6y = 72
y = 72/6 = $12
Substituting y = 12 into equation 1, it becomes
4x + 8 × 12= 128
4x + 96 = 128
4x = 128 - 96
4x = 32
x = 32/4 = $8
