Clarice Sloan is a shift supervisor for Ace
Igoryamba

The net pay is the amount left after taxes and deductions have been removed from the gross pay.

Her monthly gross pay is: $4111.93

The deductions are:

\mathbf{FIT = \$102}

\mathbf{SIT = 3.2\%}

\mathbf{CIT = 1.8\%}

Let her gross pay be x.

So, we have:

\mathbf{Net = x - FIT - x \times SIT - x \times CIT}

So, we have:

\mathbf{3804.33 = x - 102 - x \times 3.2\%- x \times 1.8\%}

Express percentage as decimals

\mathbf{3804.33 = x - 102 - x \times 0.032- x \times 0.018}

\mathbf{3804.33 = x - 102 - 0.032x -  0.018x}

Add 102 to both sides

\mathbf{3906.33 = x - 0.032x -  0.018x}

\mathbf{3906.33 = 0.95x}

Divide both sides by 0.95

\mathbf{4111.93 = x}

Rewrite as:

\mathbf{x = 4111.93 }

Hence, her monthly gross pay is: $4111.93

A rectangle on a coordinate plane is translated 5 units up and 3 units to the left. Which rule describes the trar
Citrus2011 [14]

Answer:

(x, y) → (x - 3, y + 5 )

Step-by-step explanation:

A shift of 3 units to the left means subtract 3 from the original x- coordinate.

A shift of 5 units up means add 5 to the original y- coordinate.

Thus the rule representing the translation is

(x, y ) → (x - 3, y + 5 )
