To determine the amount spent on each package of ramen, we can set up the equation based on the information given. Let \( x \) be the cost of each package of ramen.
Maggie bought 3 items, and since she bought macaroni and cheese at $1.25, the remaining cost must come from the ramen. The total amount she spent is $9.
If she bought 3 packages of ramen, we would have:
\[ 3x + 1.25 = 9 \]
Thus, the correct equation is:
3x + 1.25 = 9
