Answer:
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
[tex]6.2\ lb\approx 6\ lb[/tex]
When we round $2.85 to the nearest dollar we round up, because the digit after point is greater than 5 (8>5), so
[tex]\$2.85\approx \$3[/tex]
Now, 6.2 lb of blueberries will approximately cost
[tex]\$3\cdot 6=\$18[/tex]
Hence, Jose incorrectly rounded $2.85 down to $2. The estimate should be $18.
