Oscar has elected to have 23% of his federal income tax withheld as state income tax. If $154.00 was withheld as federal income tax on his last paycheck, how much will be withheld from his paycheck for income tax in all?

Federal income tax withheld = x

Percent held as state income tax = 0.23x

So, if $154 was held as federal income tax on the last paycheck, then the state income tax will be: 0.23 (154) = $35.42

Total income tax withheld = 154 + 35.42

$189.42
