Final answer:
Emma needs a total of 684 yards of fabric to make a blanket and two pillows, summing up the individual yard requirements for each item.
Step-by-step explanation:
The student is asking how many yards of fabric are needed to make a blanket and two pillows. The first step is to add the yards of fabric needed for each item individually. Emma needs 514 yards for the blanket, 158 yards for the first pillow, and 12 yards for the second pillow. To find the total amount of fabric needed, we will add these amounts together:
- Blanket: 514 yards
- First Pillow: 158 yards
- Second Pillow: 12 yards
The total amount of fabric Emma needs is 514 yards + 158 yards + 12 yards = 684 yards.
Therefore, the correct answer is (c) 684 yards.
