B. $1.67

Step-by-step explanation:

15% of the $96.60 only is $14.49

In order to get over 100 dollars kelly would have to purchase 5 packages of gum which is,

5 × 0.79 = $3.95.

With the gum, the total would be

$100.55 divided by 20%

= 100.55 × 100/20

= $20.11

Now, $20.11 - $14.49 = $5.62

However you need to substract the price of the gum also,

= $5.62 - $3.95

= $1.67.
