Can someone please help me with the following question :

Paul has twenty-five transit cards, each worth either$5,$3, or \$1.50. What
is the total monetary value of all of Paul's transit cards?

values of cards: 5x + 3y + 1.50(25 - x - y) = ?
Simplify ~ 3.5x + 1.5y + 37.5 = ?

From here I tried solving for x and y.. Here's what I did, please do correct me if I'm wrong (most probably am )

y = (-37,5 - 3,5x)/1,5

so, 3,5x + 1,5(-37,5 - 3,5x)/1,5 + 37,5 =
3,5x + -37,5 - 3,5x + 37,5 = x = 0

And then I got stuck

Hi

I think we need more information. This example is present there just to illustrate how to frame/imbibe maximum information from question even before reading the DS choices.

"All of the work so far has come just from the prompt of a Data Sufficiency question—you
have not even seen statements (1) and (2) yet! But this work is worth the time and energy.
In general, you should rephrase and interpret a Data Sufficiency question prompt as much
as you can before you begin to work with the statements."

Btw, I have not gone beyond this text to read any other information, so please feel free to dig further.

Regards,
Subhash

Hi, yeah so at first I thought that I can't solve it because I got 2 variables and 1 equation but then my friend (who is a math genius) said that it could be solved so I tried doing so and ended up being more confused..
