Answer:
Step-by-step explanation:

50 is little away from 49 and 50 is far away from 64.

Answer:
$200 will be price of 2 pairs
Step-by-step explanation:
It is given that the price of one pant is $80
The second is given at half price which is $40
but in the case of pants buying or anything buying when we are given an off then after buying an item the same discount is given for all
so as he bought one pant then the other pant will be given at half price
now the third pant will also be given at half price i.e: $40
fourth price will also be given at $40
so four pants will become 2 pairs
price of 2 pairs = $80+$40+$40+$40
=$200
