Final answer:

The total calories in the meal would be 630 and approximately 42.9% of the calories would come from fat.

Step-by-step explanation:

To calculate the total calories in the meal, you need to calculate the calories contributed by each nutrient. Proteins and carbohydrates each provide 4 calories per gram, while fat provides 9 calories per gram. Therefore, the total calories from protein would be 40 grams x 4 calories/gram = 160 calories. The total calories from carbohydrates would be 50 grams x 4 calories/gram = 200 calories. And the total calories from fat would be 30 grams x 9 calories/gram = 270 calories. Adding all these together, the total calories in the meal would be 160 + 200 + 270 = 630 calories.

To calculate the percentage of calories that come from fat, you need to divide the calories from fat by the total calories in the meal and multiply by 100. In this case, the percentage of calories from fat would be (270 calories / 630 calories) x 100 = 42.9%. So approximately 42.9% of the calories in the meal would come from fat.
