Answer:
202 tickets for adults were sold and 70 tickets for children are sold.
Step-by-step explanation:
Solve this question using simultaneous linear equation.
•Let the number of tickets sold for adults be a
•Let the number of tickets sold for children be b
The question stated that 272 tickets were sold altogether. So:
Now, make sure that only one of the unknown values remain on the left hand side. For example:
I will refer to the above equation as equation 1.
Now, the question also stated that the tickets sold $1694. This means that:
I will refer to this equation as equation 2.
Now, substitute equation 1 into equation 2 by replacing the a in equation 2 with the values on the right hand side in equation 1. For example:
Then just solve the equation by finding the value of b.
Lastly, find the value of a. Just take the value of b and then substitute into equation 1.
