Question

Shannon paid $57.25 for 28 pounds of potatoes. Shannon estimated the cost per pound to be $3.00. What is her error?

Answer 1

She rounded her estimation up.

Explanation:

Shannon paid $57.25 for 28 pounds ($57.25÷28=2.0446428571)

If you round the answer to the nearest dollar, you'll look at the number in the tenths place (0). Zero is not 5 or greater. That makes the 2 stay the same.
