Answer:
4.002 x 10^3
Step-by-step explanation:
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%
The answer is 10 because 5 10 15 20 25 30 35 40 45 50
