Crestwood paint supply had a beginning inventory of 10 cans of paint at $25.00 per can. they purchased 20 cans during the month at $30.00 per can. they had an ending inventory valued at $500. how much paint in dollars was used for the month?

OK, you have ten cans of paint worth 25 dollars a can. this gives you a grand total of 250 dollars worth of paint. Then you have 20 cans worth 30 dollars a piece, giving you a grand total of six hundred dollars. you would then add 250 to 600, giving you 850 dollars worth of paint. Then subtract 500 dollars. this will tell you that 350 dollars worth of paint was used.

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.
