Step 1 :Given that William Petra's earnings for the current pay period is $501.26 and the FICA rate is 6.2%.
Step 2 :To find the FICA tax deducted from William's current gross earnings, we need to multiply his earnings for the current pay period by the FICA rate.
Step 3 :First, convert the FICA rate from percentage to a decimal by dividing by 100. So, \(6.2\% = \frac{6.2}{100} = 0.062\).
Step 4 :Next, multiply this decimal by William's earnings to find the FICA tax. So, \(FICA\ tax = 0.062 \times 501.26 = 31.07812\).
Step 5 :Rounding to the nearest cent, the FICA tax deducted from William's current gross earnings is approximately $31.08.
Step 6 :Final Answer: The FICA tax deducted from William's current gross earnings is approximately \(\boxed{31.08}\).
