Then subtract the calories Corey ate to find the net calories Cary burned: 450 calories - 200 calories = 250 calories. So the final answer is 250. <ibo> Nke mbụ, chọpụta calorie ole ije ahụ gburu site n'ịmụba calorie ndị e gburu n'otu kilomita site n'ọnụ ọgụgụ kilomita ndị Cary jere: kilomita 3 * calorie 150 n'otu kilomita = calorie 450.
