Answer:
about 80 cents
Explanation:
I'm not sure what the answer is based on wording of the question, but if could be two possible answers.
If each pair of pants cost 49.50, it would be 40*49.5 = 1980
The more probable answer is if the total cost was 49.5, meaning that each pair of pants cost 40/49.5 = 0.8080808..
