If you need at least 300 calories per meal and you eat 3 meals a day, what is the minimum total number of calories needed per day?

1000

1100

800

900

To find the minimum total number of calories needed per day, you multiply the number of calories required per meal by the number of meals:

\[
300 \text{ calories/meal} \times 3 \text{ meals/day} = 900 \text{ calories/day}
\]

So, the correct answer is **900** calories.
