In one month Holly 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? Round the answer to the nearest dollar.
In one month, Holly earned $800. From those $800, 50 dollars were withheld for federal income tax. We suppose that next month, she earns $1200. Let x be the amount withheld for federal income tax, in dollars. We'll use the rule of three.
$800 ---> $50 $1200 ---> x
x = (1200*50) / 800 x = 60 000 / 800 x = 75
So next month, 75 dollars out of 1200 will be withheld for federal income tax. Hope this helps! :)
