D. 425
E. 488
calorie intake per week = 4 * (450 + 2*550) + 3 * 5*300 = 4 * 1550 + 3 * 1500 = 6200 + 4500 = 10700
after 4 week total calorie = 4 * 10700
number of meal per week = 12 + 15 = 27
total number of meal per week = 4 * 27
calorie intake per meal = 4 * 10700 / 4 * 27 = 394
Answer B
A. 386
B. 394
C. 411
D. 425
E. 488
calorie intake per week = 4 * (450 + 2*550) + 3 * 5*300 = 4 * 1550 + 3 * 1500 = 6200 + 4500 = 10700
after 4 week total calorie = 4 * 10700
number of meal per week = 12 + 15 = 27
total number of meal per week = 4 * 27
calorie intake per meal = 4 * 10700 / 4 * 27 = 394

Hi winterschool. On the first 4 days, the calorie intake is increased by 100 calories in each subsequent meal.
Calorie intake in 1 day for the first 4 days = 450 + 550 + 650 = 1650
Calorie intake for 4 days = 6600
Calorie intake for 1 day for the next 3 days = 300 * 5 = 1500
Calorie intake for the 3 days = 1500 * 3 = 4500
Total calorie intake = 11100
Total meals = (4 * 3) + (3 * 5) = 27
Therefore Calories / meal = 11100/27 = 411.11 which is approximately 411 calories.
