Question 1176639
<br>
I can't imagine that you could POSSIBLY have looked at your post before you posted it....<br>
And I can't imagine, with the way the problem is stated, that the other tutor purported to understand the given information....<br>
Perhaps with the person's name being Jérémy, the original problem was in Hungarian and was translated poorly.<br>
Or perhaps the problem was dictated orally and the voice recognition program did a poor job of translating it into words....<br>
--------------------------------------------------------------<br>
"Jérémy passes a backpack, but he wants to buy a bigger one..."<br>
From the context, he has a backpack but want to get a bigger one; maybe "passes" is supposed to be "possesses"?<br>
--------------------------------------------------------------<br>
"The capacity of the model A is 2 times greater than that of the backpack it already has."<br>
The "it" to replace "Jérémy" suggests that maybe the problem was indeed translated poorly from its original language.<br>
And even disregarding the other sloppy language, there is a fatal flaw in the statement of the problem in this sentence.  Saying that the capacity of model A is "2 times greater than..." is probably intended to mean 2 times AS GREAT AS; but 2 times GREATER THAN x means x, plus 2 more times x, which is 3x, or 3 times AS GREAT.  So we don't know whether that statement is really supposed to mean the capacity if 2 times as great or 3 times as great.<br>
--------------------------------------------------------------<br>
"As for the model B, it can hold 15 L more than its walking backpack."<br>
"its walking backpack"???!<br>
There is that "it" again that presumably has replaced "Jérémy"; but what on earth is a walking backpack?<br>
--------------------------------------------------------------<br>
For goodness sake, take the time to make your posts in such a way that we know what the question is.  You are wasting our time (and yours) by posting garbage like this.<br>
