Answer :

Using proportions, the compound inequality describes the range of incomes x for which the tax was between $450 and $600 is:

A. 3000≤x≤6000.

What is a proportion?

A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.

3% of 10000 is given by:

300

The tax was of $450 when:

450 = 300 + 0.05x.

0.05x = 150

x = 150/0.05

x = 3000.

The tax was of $600 when:

600 = 300 + 0.05x.

0.05x = 300

x = 300/0.05

x = 6000.

Hence the compound inequality is:

A. 3000≤x≤6000.
