Question

Marc's workout consists of swimming and practicing yoga. While swimming he burns 7 calories per minute, and while practicing yoga he burns 5 calories per minute. Marc wants to burn at least 400 calories each day. Let x be the number of minutes he spends swimming and let y be the number of minutes he spends practicing yoga. Write an inequality that models this situation.

Answer 1

7x + 5y ≥ 400

Explanation:

Given:

Swimming burns = 7 calories per minute

Yoga burns = 5 calories per minute

At least calories burn = 400

Total minutes of swimming = x

Total minutes of yoga = y

Find:

Inequality

Computation:

7 calories per minute(Total minutes of swimming) + 5 (Total minutes of yoga) ≥ 400

7x + 5y ≥ 400
