Nico paid $15.32 for 4.3 pounds of blueberries. nico estimated the cost per pound to be $5.00. which statement explains nico’s error? (a) nico rounded $15.32 to $15.00 and 4.3 pounds to 6 before dividing. (b)nico rounded $15.32 to $15.00 and 4.3 pounds to 3 before dividing. (c)nico rounded $15.82 to $16.00 and 4.3 pounds to 4 before dividing. (d)nico rounded $15.32 to $10.00 and 4.2 pounds to 2 before dividing.

Let's check each other to options. So each option has to get $5.00 or it doesn't explain his error.
Option A:
He rounded to $15 and rounded the pounds to 6.
15÷6= $2.50
So option a can't be the option since you get $2.50 and not $5.00
Option B:
He rounded to $15.00 and rounded the pounds down to 3.
15/3=5.00
Option B has to be the answer since you're getting $5.00.
We can check the others.
Option C:
16.00/4=$4.00
10/2=$5.00
With D, it has 4.2 which isn't the amount of pounds. Also, the rounding is a bit extreme.
So Option B explains Nico's error.
