    Weighted Average

    I have the following formula:
    E = (b+4p+w)\6

    I Use the weighted average with the following weights for b, p and w respectively: 1:5:2

    Given values​​:
    b = 5
    p = 15
    w = 18

    How do I find the value of E ?

    The answer is:
    14,43

    I've tried and not of the correct value
    b = 5/8
    p = 75/8
    w = 9/2

    E = 341/48 = 7,1041666
