if you want to simplify 4 pounds you want to make it as simple as possible: 1 pound. what do you do to get it to one pound? you divide by 4. now, whatever you do to that you do to the price so 6.48 / 4.
6.48/4=1.62 1.62
so: that means the unit price (one pound of fruit) costs exactly $1.62
It has to do with the unit circle, I think it is A because it should be 2(0+ (-1)) but I would probably wait for someone to come behind me and explain it better sorry couldn't help more
