Think about other benefits the Millers and Carpenters might receive. Part of the Millers’ income probably comes from Social Security. Perhaps the Carpenters send a preschooler to a federally funded Head Start nursery school. Because of their income level, the Carpenters also qualify for free milk at school. Next, think about what other taxes the Millers and Carpenters might be paying.
How does their state’s income tax and sales tax affect each?

Unclear question, but I infer you referring to a scenario provided by the IRS which I attached as an image.

Explanation:

Since it is noticeable from the image that the Millers earn more income than the Carpenters we expect them to have higher state income tax (following the rules of the progressive system). And they will pay more sales tax, because they're likely to spend more on purchases.

However, the reverse will be true of the Carpenters family.

explanation:

the national defense education act had two main goals. the first one was to provide personal that was oriented to defense, including scholars, engineering students and so on. the other goal was to provide financial assistance for the students who would be enrolling at colleges and universities in the 1960s.
