Need help in a DS problem.

Hi everyone , i am not sure if this is a simple one or not , but pleas send me your feedback and your methodology.. thanks.

A girl wishing to spend as much of her $5 as possible, i.e., reduce the amount of
change, in a shop where she can buy burgers, fries or both. Can she decide what
to buy?
(1) She would get the same change from buying 4 burgers as she would from
buying 6 portions of fries
(2) The burgers are 50% more expensive than the fries

[Pharo]

Let b mean price of burger, f mean price of fries.

Statement 1 : 4b = 6f --> 2b = 3f
Statement 2 : b = 1.5f --> 2b = 3f

Since there are two variables and only one equation, she cannot decide ..

At least this is what i'd have said.
