Final answer:
Sarah used 1.25 cups of sunflower seeds over 5 days by filling the feeders with 1/4 cup of seeds daily.
Step-by-step explanation:
To answer how many cups of sunflower seeds Sarah used, you would multiply the amount used each day by the number of days she fills the feeders. Sarah uses 1/4 cup of sunflower seeds each day. Over 5 days, she uses:
1/4 cup/day × 5 days = 5/4 cups = 1.25 cups
Thus, Sarah used 1.25 cups of sunflower seeds in total.
