Final answer:
The equation -1 1/2 × 4 = -6 indicates that Evie has lost a total of 6 kilograms of muscle mass over four months. The negative sign in the result signifies a loss. Hence, the correct answer is option C, which states that Evie lost a total of 6 kilograms of muscle mass.
Step-by-step explanation:
The situation described involves Evie losing muscle mass due to a cessation of exercise following an injury. The mathematical equation provided, -1 1/2 × 4 = -6, serves to calculate her total muscle mass loss over the period of four months.
To interpret the product, -6, we look at each part of the equation. The negative sign indicates loss, 1 1/2 kilograms represents the amount of muscle mass lost per month, and 4 is the number of months she hasn't been exercising. Multiplying these together, the equation gives us the total loss over the four months, which is 6 kilograms of muscle mass. Therefore, the correct interpretation of the result -6 is that Evie lost a total of 6 kilograms of muscle mass during the four-month period.
Based on the information given about the weight loss, the correct answer corresponds with option C. This is because Evie has been losing a consistent amount of muscle mass each month, and the result of the equation cumulatively represents her total loss over the specified timeframe.
