Miguel made $40,000 in taxable income last year. Suppose the income tax rate is 10% for the first $7000 plus 16% for the amount over $7000. How much must Miguel pay in income tax for last year?

In all honesty, there really is no “work” per say to show. mainly it’s just using the process of elimination. the question is asking which domain(s) would be the most appropriate for the function c(n). n is the number of observed vehicles so right away, 1, 2, and 3 can be eliminated.why? 1, 2 start in the negatives and therefore it is impossible to observe negative cars. so, #4 would be the best answer to the given problem.

Sorry i meant b in the other question
