Final answer:
To calculate the tax amount Elijah pays, which is 25% of his earnings, multiply his annual income of $18,400 by 0.25, resulting in $4,600 paid in taxes.
Step-by-step explanation:
Elijah earns $18,400 per year. To find out the amount of taxes that is 25% of his total earnings, you would simply calculate 25% of $18,400. This is accomplished by multiplying his total earnings by the tax rate in decimal form.
To convert a percentage to a decimal, divide by 100. Therefore, 25% becomes 0.25. The tax Elijah pays is then:
0.25 × $18,400 = $4,600
So, Elijah pays $4,600 in federal, state, and local community taxes.
