Disney held a breakfast for parents and their children to eat with Mickey Mouse. Adult tickets cost $17.95 and children tickets cost $12.95. Disney made $7,355 in ticket sales from a total of 500 people that attended

Children attended    x  =  324

Adults attended   y  =  176

Step-by-step explanation:

Let call "x" number  of children tickets or simply number of children

and "y" number of adult tickets, then

x  +  y  = 500   and             (1)

17.95*y + 12.95*x  =  7355 (2)

As we can see we have a two equations system. We have to solve to get x, and y

Then from equation (1)    y  = 500 -x

and plugging this value in equation  (2)

17.95* ( 500 - x )  + 12,95*x  =  7355

9875 - 17.95*x  + 12,95*x  = 7355

8975  - 5*x  =  7355

- 5*x  =  - 8975  + 7355

- 5*x  =  - 1620

x  = 1620 / 5

x = 324       And     y   =  500 -  324       y  = 176

the answer is d
