9-104.
1. For workers in the same tax bracket, the amount of money withheld for taxes varies directly with the individual’s income. When Kyleah worked in June, she earned $1537 and had$110.11 in federal taxes withheld. Homework Help ✎

1. What is the value for the constant of proportionality? What does it represent in the context of the problem?

2. If Kyleah had $128.17 withheld in July for federal taxes, how much did she make? 3. Kyleah’s mother made$5476 and had \$759.31 federal taxes withheld. Is this consistent with Kyleah’s withholding? Why is it different?

759.31 = 5476 (withholding)
Is the withholding for Kyleah's mom the same as for Kyleah?
