Megan exercises every morning for 40 minutes. She does a combination of step aerobics, which burns about 11 calories per minute, and stretching, which burns about 4 calories per minute. Her goal is to burn 335 calories during her routine. Write a system of equations that represents Megan's morning workout.

  • Math -

    x = minutes of aerobics
    y = minutes of stretching

    x + y = 40
    11x + 4y = 335

    It is possible to solve those two equations for both x and y, but they are only are asking for the equations.

    In case you are curious, x = 25
