Here are data regarding the sales of P, S, and F:   P S F Sales in State X $1,500,000 $0  $0 Sales everywhere $2,500,000 $1,500,000  $1,000,000 State X requires combined unitary reporting and allows a taxpayer member the option of computing taxable income using either a water’s-edge combination or a worldwide combination. How much higher is P’s taxable income if the income and factors of F are included in the combined unitary report?
