Practice modeling and solving systems of linear
inequalities.
Joshua wants to burn at least 400 calories per day, but
no more than 600. He does this by walking and playing
basketball. Assuming he burns 4 calories per minute
walking, w, and 5 calories per minute spent playing
basketball, b, the situation can be modeled using these
inequalities:
4w + 5b 2 400
4w + 5b s 600
Which are possible solutions for the number of minutes
Joshua can participate in each activity? Check all that
apply.
40 minutes walking, 40 minutes basketball
60 minutes walking, 20 minutes basketball
20 minutes walking, 60 minutes basketball
50 minutes walking, 50 minutes basketball
60 minutes walking, 80 minutes basketball
70 minutes walking, 60 minutes basketball
