Answer: 8 to 9 or .8888888888888888889
Step-by-step explanation:
Let a and c represent, respectively, the price of an adult and a child ticket. We know that

Multiply the first equation by 3 and the second equation by 2 to get

Subtract the two equations to have

Plug this value in the first equation to get

The product of 379 and 8 is 3032, that other answer was wrong they answered with the sum (addition) not the product (multiplication)
You cannot find the answer to 4x+120 without knowing x, otherwise it is simplified as far as it can be
The answer of this problem is A because 3 times 21 is 63 and then you plus 1
which is 64
