For this case we must find the unit cost of bananas, that is, one pound of banana. For this, we make a rule of three:
4lb -----------> $ 1.92
1lb -----------> x
Where the variable "x" represents the cost of a pound of banana.
[tex]x = \frac {1 * 1.92} {4}\\x = 0.48[/tex]
Thus, the banana pound costs $ 0.48.
If we round we have $ 0.50
ANswer:
$ 0.48
