Answer:
No; 1,200 will cause her to exceed 1,500.
Explanation:
Luna has,
→ consumed 900 cal
→ burned 500 cal
She wants to keep her daily calorie,
→ 1,500 cal/day
Calories she have left to consume,
→ 1500 - (900 - 500)
→ 1500 - 400
→ 1100 cal
Hence, she has to consume 1100 cal more to reach 1,500 cal/day.
