The sample appears to have gone through 3 half-lives
1st half life: 1000 to 500 g
2nd half life: 500 to 250 g
3rd half life: 250 to 125 g
The duration of a half-life, therefore, can be inferred to be 66 ÷ (3) = 22 days.
After a 4th half life, there will be 125÷2= 62.5 g.
At this point, an additional 22 days will have passed, for a total of 88 days.

Answer:
<em>The position is shown in the vertical axis</em>
Explanation:
<u>Position vs Time Graph
</u>
We can plot the measurements of the position of an object as a function of the time elapsed since the experiment began. Time is usually the independent variable because we measure the position of the object at specific times, fill up a table, and plot the values in our X-t coordinates system. The time, being the independent variable goes in the horizontal axis, and the position goes in the vertical axis. An example is shown below
During the cookie mining experiment, the student had to choose the tools to perform the experiment. These tools of course cost money.
Now, if the way the student conducts his/her experiment is not optimized, the student would have to spend more money and time to get the experiment done.
This also applies to real life where you have to optimize the procedures of getting any task or project completed. Otherwise, you will find yourself paying more money and consuming more time to get the output.
Another perspective of seeing how "time is money" is when a certain company/factory abides by a contract to deliver certain goods in specific time. If the company/factory fails to deliver the goods, it will pay a penalty for this delay.
Based on the above, time is money in most aspects of life. Therefore, you must always try to optimize your work.
