Please only answer this question using text so that I can better understand it.
A woman works out by running and swimming. When she runs, she burns 7 calories per minute. When she swims, she burns 8 calories per minute. She wants to burn at least 336 calories in her workout. Write an inequality that describes the situation. Let x represent the number of minutes running and y the number of minutes swimming. Because x and y must be positive, limit the boarders to quadrant I only. Show your work.
Explanation / Answer
since it is given that: x and y must be positive
x0
y0
total calories burn in x minutes by running=7x
total calories burn in y minutes by swimming=8y
so,
x0
y0
7x+8y336
hence these are our required inequalities
