Aman pays 20 percent of his total income in tax. his weekly tax is $100. what is his total weekly income?

$500

Step-by-step explanation:

A man pays 20% of his total income in tax.

His weekly tax = $100

Let his total weekly income = x

He pays income tax =  20% of x = 100

                                 = 0.20x = 100

                              x = 100 ÷ 0.20

                                 = 500

His total weekly income is $500.

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is
