Sharifah earned $61,000 last year. If the first $34,000 is taxed at 11% and income above that is taxed at 17%, how much does Sha

Marina CMI [18]

Using proportions, it is found that Sharifah owns $8,330 in taxes.

<h3>What is a proportion?</h3>

A proportion is a <u>fraction of total amount</u>, and the measures are related using a rule of three.

Hence, using proportions, a percentage x% of an amount a is given by: $\frac{x}{100} \times a$ .

<h3>Taxes for the first $34,000:</h3>

Rate of 11%, hence:

$T_1 = 0.11(34000) = 3740$

<h3>Taxes for the amount above $34,000:</h3>

The amount taxed is $27,000, as 61000 - 34000 = 27000.

Rate of 17%, hence:

$T_2 = 0.17(27000) = 4590$

Then, the total amount is:

$T = T_1 + T_2 = 3740 + 4590 = 8330$

Sharifah owns $8,330 in taxes.
