Assume a tax rate of 6.2% on $128,400 for Social Security and 1.45% for Medicare. No one will reach the maximum for FICA. Comple
Yakvenalex [24]

Answer:

  • FIT: $340.76 (see comment)
  • OASDI: $173.60
  • Medicare: $40.60
  • Net Pay: $2245.04

Step-by-step explanation:

In addition to the information given in the problem statement, we need to know the applicable tax rates and allowance deductions. If we assume the tables we found (attachments 1 and 2) are the same as those in your text, the one additional fact needed is the gross pay to date. At the given wage rate, paychecks after the 44th week will have reduced FICA tax deductions.

Allowances: 4 × $79.80 = $319.20

Adjusted gross pay for FIT: $2800 -319.20 ≈ $2481 (rounded to nearest $)*

FIT: 0.22 × (2481 -1711) +171.36 = 0.22×2481 -205.06 = 340.76

Social Security & Medicare: 0.0765 × 2800 = 214.20

Net pay = $2800 -340.76 -214.20 = $2245.04

_____

<em>* Comment on rounding</em>

The IRS gives the option of rounding the pay or the tax, as long as it is consistently done. Here, the amount of tax on the unrounded gross pay would be 4 cents less: 340.72. The option of reducing the last digit of pay to zero is also offered. FIT on 2480 would be 340.54.

The areas of two similar triangles are 20m2 and 180m2. The length of one of the sides of the second triangle is 12m. What is the
guajiro [1.7K]

Answer:

The corresponding side of the first triangle is 4 m.

Step-by-step explanation:

Area of the first triangle: A1=20 m^2

Area of the second triangle: A2=180 m^2

Lenght of one of the sides of the second triangle: s2=12 m

Corresponding side of the first triangle: s1=?

A1/A2=(s1/s2)^2

Replacing the known values:

(20 m^2)/(180 m^2)=[s1/(12 m)]^2

Simplifying:

2/18=[s1/(12 m)]^2

Simplifying the fraction on the left side of the equation dividing the numerator and denominator by 2:

(2/2)/(18/2)=[s1/(12 m)]^2

1/9=[s1/(12 m)]^2

Solving for s1: Square root both sides of the equation:

sqrt(1/9)=sqrt{[s1/(12 m)]^2}

sqrt(1)/sqrt(9)=s1/(12 m)

1/3=s1/(12 m)

Multiplying both sides of the equation by 12 m:

(12 m)*(1/3)=(12 m)*s1/(12 m)

Simplifying:

(12 m)/3=s1

4 m=s1

s1=4 m
