There are museums in the united states. a.) 5,500 b.) 10,500 c.) 17,500 d.)25,500

there are 35,144 museums in the U.S. currently I believe but more than double the agency's working estimate of 17,500 from the 1990s.

so im going to say the answer is C since the answer is exact? because idk if you mean modern todays date or 1990s

b.

jim crow laws were enacted in northern states.

the correct answer is “opportunity cost”. opportunity cost is what a company misses out because it decided in one option over another one. in this case, the company decided to invest in building a factory so it gave up another possible benefit or profit in order to achieve success with the factory.  

trade-off is not the correct answer since it is a situation in which you accept losing something in return for benefits in other areas.

and finally, consequence is a general term used to accept what it comes when you make a decision. it can be a positive or negative consequence depending if the decision you took was the correct one.
