1 and 2 conditions state the same: each notepad costs less than $1

A) Let a notepad costs 0.00001$ and a marker costs 0.00001$. It this case we can buy 4 notepads and 4 markers instead. B) Let a notepad costs 0.00001$ and a marker costs 9.9/3=3.3$. It this case we cannot buy 4 notepads and 4 markers instead. _________________

Both statement 1 and statement 2 tell you about the max price of x (notebook).

Neither one of them gives any indication around the max price for y (marker). As a result, even when you use both statements together, you cannot determine the max price for the marker. That's where you are making a mistake.

If the marker is $1, then it true. If the marker is $1.83 as I showed in my example, then false.

(1) each notepad costs less than $1.

(2) $10 is enough to buy 11 notepads.

Given: \(5x+3y\leq{10}\). Question: is \(4x+4y\leq{10}\)?

Note that both statements are telling us basically the same thing:

Now, if both notepad and marker cost very cheap then the answer would be YES but if notepad costs $0.1 and marker costs $3 then the answer would be NO. Not sufficient.
