Final answer:
Leena consumes 400 calories at breakfast and 350 calories at lunch, but there is no solution for the number of calories consumed at dinner.
Step-by-step explanation:
Leena consumes 400 calories at breakfast and 350 calories at lunch. Let x represent the calories consumed at dinner. Since Leena consumes 2/3 of her daily calories at dinner, we can set up the equation:
400 + 350 + x = 2/3 * (400 + 350 + x)
Simplifying the equation:
750 + x = 2/3 * (750 + x)
Multiplying both sides by 3:
2250 + 3x = 1500 + 2x
Subtracting 2x from both sides:
2250 + x = 1500
Subtracting 2250 from both sides:
x = -750
Since it doesn't make sense for the number of calories to be negative, we can conclude that there is no solution to this equation. Therefore, none of the statements describe the situation.
