Write an equation for each problem: 1) ally had $24 to spend on 7 pencils. after buying them, she has $10 left. how much was each pencil? 2) a catering company charges $10 per person, plus a set-up fee of $200. if you have a budget of $400 for your party, how many people can you invite?

1) 24-10= 14 then 14÷7=2 so each pencil was $2

2) so you can already take of $200 because you need it no matter what so: 400-200=200 then 200÷10=20 so 20 peaple can be invited

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.
