Final answer:
Cora had $4.95 left for gift C.
Step-by-step explanation:
To find out how much money Cora had left for gift C, we need to calculate the total amount of money she had at the beginning and subtract the amounts she spent on gifts A and B.
First, let's calculate the total amount of money she had at the beginning: $20
Next, let's calculate the amount she spent on gift A: $11 rac{1}{4} = $11.25
Now, let's calculate the amount she spent on gift B: $3 rac{4}{5} = $3.80
To find out how much money she had left for gift C, we need to subtract the amount spent on gifts A and B from the total amount she had at the beginning: $20 - ($11.25 + $3.80) = $4.95
Therefore, Cora had $4.95 left for gift C.
