Big Mac has 550 calories
Chicken Nugget has 275 calories
Grilled Chicken Sandwich has 350 calories
Total number of calories = 1175
Let the number of calories in Big Mac = x
Since the 6-piece chicken nugget meal has half the calories of the Big Mac. Therefore, the number of calories in the chicken nugget = 1/2 × x = 0.5x
Since the Grilled Chicken Sandwich has 200 less calories than the Big Mac. This will be: = x - 200
To calculate the number of calories in each food goes thus:
x + 0.5x + x - 200 = 1175
Collect like terms
x + 0.5x + x = 1175 + 200
2.5x = 1375
Divide by 2.5
2.5x/2.5 = 1375/2.5
x = 550
Big Mac has 550 calories
Chicken nugget will have:
= 0.5x = 0.5 × 550 = 275 calories
Grilled Chicken Sandwich will be:
= x - 200
= 550 - 200
= 350 calories
