To find out how many more pounds of licorice Marri bought than candy worms, we subtract the amount of candy worms from the amount of licorice.
Marri bought:
- Licorice: 12 pounds
- Candy worms: 13 pounds
Now, we perform the subtraction:
\[ 12 , \text{pounds (licorice)} - 13 , \text{pounds (candy worms)} = -1 , \text{pound} \]
This result indicates that Marri bought 1 pound less of licorice than candy worms.
Thus, the answer is that she did not buy more pounds of licorice than candy worms; in fact, she bought 1 pound less.
