the unit price is $3 per pound, the correct option is the second one.
The unit price for the oranges is just the price for one pound of oranges.
Here we know that the price of 4 lb of oranges is $12, with that we want to get the cost of a single lb of oranges, so we can write:
4lb = $12
If we divide both sides by 4, then we get:
4lb/4 = $12/4
1lb = $3
This means that the price of 1 pound of oranges is $3, then the unit price is $3 per pound, the correct option is the second one.
