A high school student working part-time as a cashier had a gross income of $6727 last year. If his federal tax rate was 10% and his state tax rate was 4.3%, what was the amount withheld from his pay lat year in federal tax, state tax, and FICA combined

Not enough information

Explanation:

Without knowing what the individual put on his or her W-4 or knowing the state on which he or she worked, or knowing how many paychecks this was earned over, this question cannot be answered.

Federal income tax withholding uses a bracketed system based on the assumption that each pay period is representative of the entire year. If the individual only worked part of the year, or worked irregular hours, the total withholdings will be greater than if the individual had earned the exact same pay in each of 52 (or 53) weeks.

State withholding rules vary by state. Some are flat rate, but others are bracketed.

It's also possible that this worker is exempt from Social Security taxes, so we can't even conclude that this worker had to pay the flat rate FICA tax.

There is simply not enough information to answer this question.
