What this exercise teachesMay contain the answer

Write the rule the way it is spoken: (this and that) or the other. Nesting AND inside OR keeps each route intact; flattening it into OR(B2>30000,C2>650,D2="Yes") would approve anyone with a decent credit score alone. T6 earns exactly 30,000, which is not over it.
