hi
You have to keep calm and to treat data as it come.
<u>1 ) Start by constant fees : </u>
hook up fees is 32.50 and trash collection fees are 35
so contant fees : 32.50 +35 = 67.50
2 ) Now we have to deal with variable fees which depend on how much water is used
water fees :
0.03 per gallon, and we have 4 000 gallon, so :
0.03*4 000 = 120
Sewer fees :
0.01 per gallon, and we have 4 000 gallon, so :
0.01 * 4000 = 40
3 ) Total before taxation we have :
67.50 +120 +40 = 227.5
4) Now we apply tax on the total before tax.
tax is 5 % , which mean you rise the "off tax " price by 5 percent.
<u>To grow a number of X % , you multiply by 1+ X/ 100 </u>
here X = 5 so the multiplicator is : 1 + 5/100 = 1.05
<u>So total of the bill is : 227.5 * 1.05 = 238.875 </u>
The water compagny is probably going to round it up to 238.88
