Answer:
Approximate percent error = 15%
Step-by-Step Explanation:
Let the percentage of error be "e"
Anticipated sales = 2,500
Actual sales = 2,125
The percentage error "e" can be calculated as per the equation below:
2500*(1-e) = 2125
(1-e) = 2125/2500
1-e = 0.85
e = 1-0.85
e = 0.15
e = 15%
Approximate percentage error = 15%
