The graph shows Elizabeth’s total savings over seven weeks. Did she save more money from week five to week six than any other week?

Here, in our graph, we can see Elizabeth’s savings: on the left, total savings in dollars and on the bottom are the weeks. So let’s begin by writing down how much money she had each week.

At week one, Elizabeth had about 150 dollars. At week two, Elizabeth had 140 dollars. At week three, Elizabeth had 60 dollars. So, so far, she hasn’t been saving any money from each week. She’s been losing money. But now at week four, her savings are finally increasing. And at week four, she has 80 dollars. At week five, Elizabeth has around 110 dollars. At week six, Elizabeth has 120 dollars. And then, finally, at week seven, Elizabeth decreases and it’s down to 70 dollars.

So from week one to week two, how much money did Elizabeth save? Elizabeth didn’t save. She went down 10 dollars. From week two to week three, unfortunately, Elizabeth went down 80 dollars because 140 minus 60 is 80. From week three to week four, she went from 60 dollars to 80 dollars. That’s an increase in 20 dollars. She’s saving money. From week four to week five, she saved money again. She saved 30 dollars. And then from week five to week six, she saved 10 dollars because 110 to 120 is an increase in 10. And then, lastly, from week six to week seven, we went from 120 dollars to 70 dollars. That’s a decrease in 50 dollars. So she did not save money.

So we were asked did she save more money from week five to week six than any other week. From week five to week six, she saved 10 dollars. Was that the most money she had ever saved during those seven weeks? The answer will be no because she had saved more than that. From week four to week five, she saved 30 dollars.

So once again, she did not save more money from week five to week six than any other week. Our final answer will be no.
