Question

In one month Vivian earned $800 at her part-time job, and $50 was withheld for federal income tax. Suppose she earns $1200 next month. How much will be withheld for federal income tax?

Answer 1

Let's use a rule of three:

Therefore,

`x=(1200\cdot50)/(800)\rightarrow x=75`

We can conclude that $75 will be withheld for federal income tax.
