Brandi and amanda are buying fabric to make costumes for a musical in which they are performing. at the craft store, they select 3 7/8 yards of blue fabric,5 1/8 yards of green fabric, and 3 1/3yards of white fabric. if brandi and amanda want to split the cost of the fabric evenly, and each yard of fabric costs $7.50, about how much would brandi pay towards buying the fabric?

                                3 7/8 + 5 1/8 + 3 1/3 equals 12 1/3
12 1/3 multiplied by the cost of each yard of fabric ( 7.5) is 92.475 
92.475 divided by the 2 girls who are splitting the cost is 46.2375 which you can round up to 46.24( correct answer)

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.
