B) your local shoe store anticipated giving away 2,500 pairs of shoes in one month, but they only sold 2,215 pairs of shoes. what was the approximate percent error? show your work to find the percent error. (2 points)

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%
