A programmer is developing a game scoring system. The following pseudocode contains a procedure and two functions used to process score adjustments.

procedure CalculateScore(a, b, c)
    val = a * b
    print(AdjustScore(val, c))
endprocedure

function AdjustScore(p, q)
    total = p - q
    if total > 15 then
        total = total + ExtraBonus(p)
    endif
    return total
endfunction

function ExtraBonus(r)
    if r > 20 then
        return 10
    else
        return 4
    endif
endfunction
