Question

In a certain country, income tax T (in dollars) is assessed according to the following function of income x:

T(x) =	0	if 0 ≤ x ≤ 10,000
0.09x	if 10,000 < x ≤ 20,000
1800 + 0.11x	if 20,000 < x

Find T(5,000), T(12,000), and T(25,000).

T(5,000)	=	$
T(12,000)	=	$
T(25,000)	=	$

Answer 1

What seems to be the issue?

Since 0 ≤ 5000 ≤ 10,000, T(5000) = 0

The rest is on you.
