A new mother changes her baby's diaper 6 times a day, on average. How many diapers will the child use in a year?

Rationale

The child will use 2,190 diapers in a year.

A new mother changing her baby’s diaper 6 times a day leads to a simple calculation for a year: 6 diapers/day multiplied by 365 days/year equals 2,190 diapers. This straightforward multiplication provides the answer based on consistent daily usage.

A (2,190) CORRECT

This choice accurately reflects the total number of diapers used in a year based on the calculation of 6 diapers per day over 365 days: 6 x 365 = 2,190.

B (2,200) YOUR ANSWER

This option miscalculates the total by rounding up the daily count, suggesting an average of 6.03 diapers per day. However, the problem specifies exactly 6 diapers per day, making 2,200 an incorrect estimate.

C (2,500) YOUR ANSWER

Choosing 2,500 implies an average of about 6.85 diapers per day, which exceeds the stated average of 6 diapers. This overestimation results from incorrectly assuming a higher daily diaper change rate, deviating from the given information.

D (1,800) YOUR ANSWER

This choice underestimates the total diaper usage, suggesting an average of approximately 4.93 diapers per day. Such a figure is inconsistent with the stated average of 6 diapers daily, leading to a significant miscalculation.

Conclusion

The correct calculation reveals that a baby using 6 diapers a day results in 2,190 diapers annually. The other choices misinterpret the daily average, leading to either overestimation or underestimation of diaper usage. It’s essential to adhere strictly to the provided average to ensure accurate mathematical conclusions in problem-solving contexts.
