Shoes and hats are on sale. the expression
1/4 (s+24.80) can be used to determine the
discount when you buy shoes with a retail price of s dollars and a hat with a retail price of
$24.80. write another expression that can be used to determine the discount.

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.

Then just do it (lol)
