Final answer:
There seems to be an inconsistency in the question as Vanessa cannot use more ribbon than she has. If the given numbers were accurate, she would not have any ribbon left over after using 35 yards since she only had 10 yards to start with.
Step-by-step explanation:
The subject of this question is Mathematics, as it involves basic arithmetic operations, such as addition and subtraction, to solve a real-world problem related to measurements in yards.
Vanessa initially has 2 rolls of ribbon, with each roll containing 5 yards. So in total, she begins with 2 rolls x 5 yards/roll = 10 yards.
Since she uses 35 yards to make hair bows, but she only had 10 yards to begin with, it is actually impossible for her to use more ribbon than she has. Therefore, there appears to be a mistake in the problem statement. Assuming there is no mistake and the quantity of the initial ribbon was sufficient, the answer does not make sense since you cannot use more ribbon than you have.
If the correct amount of ribbon used should be less than or equal to 10 yards, then we would subtract the amount used from the initial amount to determine the remaining ribbon. If Vanessa actually used less ribbon than the amount she had available, we would calculate it like this: Remaining ribbon = Initial ribbon - Used ribbon. For this problem, however, with the numbers provided, there is no positive remainder and thus, none of the options (a-d) correctly answers the question based on the initial information given.
