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 = 
<gadget id="calculator">50*2</gadget>
<output>100</output>
100 calories.
Then find the total calories in the salad: 100 calories + 50 calories + 210 calories = 
<gadget id="calculator">100+50+210</gadget>
<output>360</output>
360 calories.
Then find the number of calories in the pepperoni: 1/3 * 600 calories = 
<gadget id="calculator">1/3*600</gadget>
<output>200</output>
200 calories.
Now find the total number of calories in the pizza: 200 calories + 600 calories + 400 calories = 
<gadget id="calculator">200+600+400</gadget>
<output>1_200</output>
1200 calories.
Now find how many calories are in Jackson's portion of the salad: 360 calories * 1/4 = 
<gadget id="calculator">360*1/4</gadget>
<output>90</output>
90 calories.
Now find how many calories are in Jackson's portion of the pizza: 1200 calories * 1/5 = 
<gadget id="calculator">1200*1/5</gadget>
<output>240</output>
240 calories.
Now find the total calories Jackson ate: 90 calories + 240 calories = 
<gadget id="calculator">90+240</gadget>
<output>330</output>
330 calories.
