for breakfast, randy had two egg mcmuffins and a hash brown, totaling 750 calories. Jack only had one egg mcmuffin and a hash brown, totaling 450 calories. how many calories are in each item?
Use algebra/simultaneous equations for the easy way. Let's call Egg McMuffins 'e' and Hash Browns 'h'. So 2e + h = 750 And e + h = 450 Subtract the bottom equation from the top one e = 300 Substitute e back in to the bottom equation (Because it's simpler) 300 + h = 450 Simplify the equation, subtract 300 from each side h = 150
So there you go. Egg McMuffins have 300 calories and Hash Browns have 150 calories
