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.

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

   Hint (a):

   interest = earnings (constant)The constant is the withholding rate.

   Answer (a):

   $110.11 = 1537K$
   $K = 0.07$

2. If Kyleah had $$128.17$ withheld in July for federal taxes, how much did she make?

   Hint (b):

   $128.17 = \left(\text{Withholding rate}\right) · \left(\text{earnings}\right)$

3. Kyleah’s mother made $$5476$ and had $$759.31$ federal taxes withheld. Is this consistent with Kyleah’s withholding? Why is it different?

   Hint (c):

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