The percentage error is 23%
Explanation:
The estimated total cost of the groceries = $50
The actual cost of the groceries = $65
To find the error value, we need to subtract the value of actual cost and total cost of the groceries.
Thus,
error value = actual cost - total cost
error value
Hence, error value = $15
The formula to determine the percent error is given by
Substituting the values in the formula, we get,
Rounding off the value, we have, 23%
Thus, the percentage error is 23%
Answer:
C) 0.179
