Incorrect & Missing Dialogue Text from Lesson 3.3 Advanced

In Carmen's last line, "bajas" should be "bajos." In Mauricio's last line, the following text is missing at the end: "No quiero gastar dinero que no tengo." Greg Edit: I should point out that in the opening dialogue, Carmen is saying "más bajos de los bancos." But when the dialogue is covered, and when it is repeated, she changes it to "bajas," heavily accenting the word for some reason. A clarification on this point would be nice, as I gave the sentence "We offer the lowest interest rates of all the banks" for translation to two Spanish speakers, both of whom used "bajos" instead of "bajas."
