Renee’s workout consists of biking and running. While biking she burns 10 calories per minute, and while running she burns 15 calories per minute. Renee wants to burn at least 900 calories each day.

Let x be the number of minutes she spends biking and let y be the number of minutes she spends running. Write an inequality that models this situation.

Respuesta :

Answer:

10x + 15y ≥ 900

Step-by-step explanation:

She burns 10 calories per minute while biking and 15 calories per minute while running. For each exercise, the number of minutes multiplied by the number of calories burned per minute will give the total number of calories burned.

Calories burned while biking (10x) plus (+) calories burned while running (15y) is at least 900 (≥900).

The inequality that models this situation is therefore

10x+15y≥900
