On Friday, the ratio of vanilla cones sold to chocolate sold was 2:3. if the store had sold 4 more vanilla cones, the ratio of the vanilla cones sold to chocolate cones sold would have been 3:4 how many vanilla cones did the store sell on Friday?

kindly show your solution

  • algebra/geometry - ,

    V/C = 2/3, so C = 3V/2
    (V+4)/C = 3/4

    V+4 = (3/4)C = (9/8)V
    V/8 = 4
    V = 32
    C = 48
