Give the step-by-step reasoning process and then the final answer. Jackson is making dinner. He makes a salad out of lettuce (50 calories), carrots (twice the calories of the lettuce) and dressing (210 calories). He also makes a pizza with 600 calories for the crust, 1/3 the crust's calories for the pepperoni, and 400 calories for the cheese. If Jackson eats 1/4 of the salad and 1/5 of the pizza, how many calories does he eat?
First find the number of calories in the carrots: 50 calories * 2 = 100 calories. Then find the total calories in the salad: 100 calories + 50 calories + 210 calories = 360 calories. Then find the number of calories in the pepperoni: 1 / 3 * 600 calories = 200 calories. Now find the total number of calories in the pizza: 200 calories + 600 calories + 400 calories = 1200 calories. Now find how many calories are in Jackson's portion of the salad: 360 calories * 1 / 4 = 90 calories. Now find how many calories are in Jackson's portion of the pizza: 1200 calories * 1 / 5 = 240 calories. Now find the total calories Jackson ate: 90 calories + 240 calories = 330 calories.
The final answer: 330.
