Lily went for 8 rides at the county fair. Some rides were on the merry-go-round, and the rest were on the pirate ship. The total cost of all rides was $6.30. Each pirate ship ride cost $0.60, and each merry-go-round cost $0.90. How many pirate ship did Lily take?

  • math - ,

    x+y = 8
    .6x + .9 y = 6.3

    y = 8 - x

    .6 x + .9(8-x) = 6.3

    -.3x + 7.2 = 6.3

    -.3 x = - .9

    x = 3 pirate rides
    so y = 5 merry go round rides
