The number of calories burned, c, varies directly with the time spent exercising, t. When Dennis walks for 4 hours, he burns 800 calories. Which equation shows direct linear variation for this situation? A. c = t B. c = 4t C. c = 200t D. c = 800t

OpenStudy (anonymous):

it is C. c = 200 t

OpenStudy (anonymous):

because 4hours = 800 calories so 1 hour = 800/4 = 200 so its c=200t
