When Mr. J. Raff took his two children to the zoo,their tickets cost $8.75. The next family in line was Mrs. Ella Fant with Grandpa and the five Fant kids. Their tickets cost a total of $19.75. How much does the zoo charge for each adult and for each child?

  • algebra - ,

    Raff: a + 2c = 8.75
    Fant: 2a + 5c = 19.75

    Fant - 2 x Raff:

    c = 2.25
    so a = 4.25
