jose did not make an error. his estimate of $12 is correct.
jose incorrectly rounded $2.85 down to $2. the estimate should be $18.
jose incorrectly rounded 6.2 up to 7.
jose incorrectly multiplied 2 and 7. the estimate should be $14.

Jose incorrectly rounded $2.85 down to $2. The estimate should be $18.

Step-by-step explanation:

When we round 6.2 lb to the nearest pound we round down, because the digit after point is less than 5 (2<5), so

When we round $2.85 to the nearest dollar we round up, because the digit after point is greater than 5 (8>5), so

Now, 6.2 lb of blueberries will approximately cost

Hence, Jose incorrectly rounded $2.85 down to $2. The estimate should be $18.
