OK, Here is everything broken down for you but I have to ask about number 3 which also affects number 4. I think you left out a word - Is it supposed to say 'You have 75% of your check direct deposited. How much is given to you as a check per week?' If it is saying that 75% of the check is being direct deposited into his account and he is receiving the difference of that in a check himself, the answer is $25.95. The total amount of his check that he earns, after taxes are deducted is $103.78 Please double check the wording of number 3 to put in the correct answer because I've never heard of a company paying a salary with both direct deposit and a check.
Explained as follows:
$13.76 (hourly wage) x 10 hours = $137.60
$137.60 x 7.65% (FICA) = $10.53 $137.60 x 9.8% (fed tax) = $13.48 $137.60 x 7.13% (state tax) = $9.81 $10.53 + $13.48 + $9.81 = $33.82
$137.60 - $33.82= $103.78 (total amount of his take home pay after taxes) $103.78 x 75% = $77.83 (If 75% is direct deposited but again, check wording in number 3; if true then the separate check he would take home would be $25.95)
The answer to number 4 depends on the correct wording for number 3. 50% of the total take home pay of $103.78 = $51.89 50% of the separate check, if wording for number 3 is right, of $77.83= 38.91
