1)Bradley is buying ice cream cones. a double scoop cone cost x dollars. A single scoop costs $0.50 less than a double csoop. A triple scoop cone costs twice as much a single scoop cone. Write an expression to represent the cost of 3 double scoop cones and 1 single scoop cone. 2) if x=$2 what is the cost of 1 triple scoop cone?

  • 6th grade - ,

    double cost = x
    single cost = (x-.50)
    triple = 2(x-.50)

    3 x + 1 (x-.50)
    = 4 x - .50

    triple = 2 (2-.50)
    = 2 (1.50)
    = $3.00
