Question

1 cheeseburger plus 2 tacos equal 2880 calories, 2 cheeseburgers plus 1 taco equals 2700 calories. Find the calorie content of each item

Answer 1

2(c+2t=2880)-(2c+t=2700)

2c+4t-2c-t=5760-2700

3t=3060

t=1020, since c=2880-2t

c=840

So a cheeseburger has 840 calories while a taco has 1020 calories.
