Answers

Alright so to discover the answer to your problem the first thing you need to do is add up all of your listed taxes so that you know what the total number of taxes you paid is. So adding up your 'road' taxes, 'schools' taxes, 'public safety' taxes, and 'township' taxes your total will come up to $1468. After that you simply divide your 'public safety' taxes by the total number of taxes you paid. So that means you divide 154 by 1468, thus giving you 10.49%. So of the listed options, option a (10.49%) is the correct answer.

Answer: a. 10.49%

Step-by-step explanation:

Given: The share of tax on Public facility= $154

The total amount paid as tax = $241+$896+$154+$177=$1468

The percentage of taxes went to funding public safety is given by:-

$P=\frac{\text{share of tax on Public facility}}{\text{Total tax amount}}*100\n\n\Rightarrow\ P=(154)/(1468)*100\n\Rightarrow\ 10.49\%$

Hence, The percentage of taxes went to funding public safety= 10.49%
