Anna uses 6.8 pints of white paint and blue paint to paint her bedroom walls. 3/4
of this amount is white paint, and the rest is blue paint. How many pints of blue paint did she use to paint her bedroom walls?

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.
