Dion predicted that he would sell 87 art prints. He actually sold 100 art prints. What are the values of A and b in the given table? Percent Error Item Approximate value Exact value Error Absolute error Ratio Percent error Art prints 87 100 A b

The error is the approximate value minus the exact value: 87 − 100 = −13, so A = −13. The absolute error is the distance from the exact value, ignoring the sign: |−13| = 13, so b = 13. This matches choice A.
