Being aware of quantity changes over time is important as it helps us to make informed decisions. One example would be in the medical field, when a baby is born, you track their height, weight, and head circumference percentiles to make sure the baby is developing properly. If the percentiles for a baby’s head circumference is in the higher percentiles, it can be a cause for concern and requires frequent check-ins with the doctor. If it continues to remain in the higher percentiles, they will be sent to a specialist to be sure no serious complications are occurring. Another example would be with saving money, tracking what you spend and save weekly/monthly/annually can help you to reach your savings goals. It can also help you to budget what you may need to cut back on to reach those goals. In regards to school, by looking at your grades can help you to see if you need to study harder to get better grades, or if you are studying enough to maintain good grades. In your home, by looking at your electric bill, you can estimate the cost difference between summer and winter so you know how much you will spend between the seasons. My electric bill tends to be a lot higher in the summer due to running the air conditioner, and cheaper in the winter, so I know I need to be mindful of this cost change and set aside extra funds in the summer to cover those costs.

Hello,
I think being aware of quantity changes helps me make sound decisions. In majority of the situations quantity is a factor, rather it be time, money, cost, distance, or others. Knowing if the quantity changes are positive or negative will help me decide on which route to take since I am more than likely looking for an increase of quantity depending on the situation at hand. There are many examples of quantity changes, the first one I think of would be the quantity of time that I have left at work as the time passes throughout the day, the quantity of time also decreases. That is one instance where I am happy to see quantity decrease. Another example would be when I am cooking a certain meal and needing to increase the quantity to ensure that I have enough food to feed everyone when there are more people eating than my normal family size. The last example would be the quantity of time it takes to travel somewhere changing based on the speed that you are traveling at.
