Final answer:
Ellen had 12,080 Legos and she lost 417. By subtracting these numbers, we conclude that Ellen now has 11,663 Legos remaining.
Step-by-step explanation:
The problem presents a simple subtraction operation involving the number of Legos that Ellen initially had and the Legos she lost. To solve, we just need to subtract 417 (the number of lost Legos) from 12,080 (Ellen's initial number of Legos). Using this operation: 12,080 - 417, the answer equals 11,663 Legos which corresponds to option a) in your given choices. So, Ellen now has 11,663 Legos after losing 417.
