Water tank holds 711 gallons but is leaking at a rate of 4 gallons per week. second water tank holds 948 gallons but is leaking at a rate of 7 gallons per week. After how many weeks will the amount of water
in the two tanks be the same?

After 79 weeks the tanks will have the same amount of water.
948-7*79=395
711-4*79=395

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.
