Refer to the exhibit.

According to the Calculation Matrix Overview page, a Calculation Matrix is “a lookup table that takes an input and returns an output”. In this case, the input is the ProductCode and the output is the Price. The exhibit shows a Calculation Matrix with four rows, each with a different ProductCode and Price. The input given is ProductCode: HRA3320, which matches the second row of the matrix. Therefore, the output is Price: 13.99, which is the value in the same row.
