I was teaching ESL class and came across a sentence "If you asked me, I would apologize and tell you I was too busy". A student in the class asked the reason why "I was too busy" is used instead of "I am too busy".

Verbforms in a conditional like this, employing what we used to call "reported" speech, without direct quotation, will be shaped by the context—specifically, the verbform in the clause representing the speech will depend on whether the hypothetical "scopes" over the subordinate clause.

A: What would you say if I asked you to have dinner tonight?
B: I would apologize and say that I'm too busy—I have papers to grade.

Here the context is a question about B's hypothetical action (what would you say) respecting a possible and knowable future action. Since as a matter of actual fact B is not free, she responds with an ordinary indicative.

C: You don't know how to say No. If you were really really busy and I asked you to dinner, you'd go, even if it meant staying up all night grading papers.
B: That's not true. I would apologize and say I was too busy.

Here the context is an allegation about B's hypothetical action (you would go) in a hypothetical situation (if you were busy). Since B's denial does not reflect an actual situation but a hypothetical situation, she responds with a past form—what the Cambridge Grammar of the English Language calls a "modally remote" use of the past.
