Answer:
{x + y= 239
{15x + 5.50y = 2758.50
Step-by-step explanation:
x = adults y = children and the total amount of people is 239.
$15 for adults and $5.50 for children and the total cost equals $2758.50.
An odd number of rolls of pennies ($0.50 each) cannot be part of the solution, making answers A and D not worthy of consideration.

Answer:
☑ (¼, 0)
Step-by-step explanation:

» Assume y is zero:

First see you can factor out 4. What is left is x^2 + 6x - 16.
That can be factored as (x+8)(x-2) so the total factorization is
4(x+8)(x-2)
