Answer: I think random sample
Step-by-step explanation:
Answer:
B
Step-by-step explanation:
From annual salary of 42,600, we have to subtract the following percentages:
<u>Social Security:</u>
0.062 * 42,600 = 2641.2
<u>Medicare:</u>
0.014 * 42,600 = 596.4
<u>State Income Tax:</u>
0.03 * 42,600 = 1278
<u>Federal Income Tax:</u>
0.13 * 42,600 = 5538
<u>Total Deductions</u> (from percentages) = 2641.2 + 596.4 + 1278 + 5538 = 10053.6
Now, remaining salary:
42,600 - 10053.6 = 32546.4 (annual)
Divided by 12 to get monthly:
32546.4 / 12 = 2712.2 (monthly)
Now, monthly deductions are:
260 + 280 = 540
<u>Net Salary:</u> 2712.2 - 540 =2172.2
