Answer:
She would collect $27.
Step-by-step explanation:
A dozen means that it is a set of twelve items, so in order to find the amount of cupcakes she sold, you have to multiply 12 for the number of dozens she baked which was 3:
12*3=36
Now that you know the number of cupcakes she sold, you have to multiply this for the price of each cupcake:
36*$0.75= $27
According to this, the answer is that she would collect $27.
