To solve this problem, we need to follow the given information step by step.
1. Cara baked 16 cupcakes initially.
2. She gave Tracy one-fourth of what she had left.
- To find out how many cupcakes Cara had left, we calculate three-fourths of the total cupcakes.
- Three-fourths of 16 cupcakes is (3/4) * 16 = 12 cupcakes.
3. Cara gave Tracy 12 cupcakes.
4. To find out how many cupcakes Cara has now, we subtract the cupcakes given to Tracy from what Cara had left.
- Cara had 12 cupcakes left - 12 cupcakes given to Tracy = 0 cupcakes.
Therefore, Cara has 0 cupcakes now.
In summary, Cara gave Tracy 12 of the initial 16 cupcakes she baked and now does not have any cupcakes left.
