Answer:
a. $19.00
Explanation:
Note: The graph is as attached below
The low of the column where a quadruple top breakout occurs is $8.5 and width is 7 and box size is 0.5
The width of the pattern is 7 which is multiplied by 0.5 which is the box size and the reversal size of 3 for an Extension estimate (7 x 0.5 x 3 = $10.5).
Now, $10.5 is added to the low of the column and hence price objective is $10.5 + $8.5 = $19
