The total cost of water for one year in Community Z of 120,000 homes is $75,000. If the cost were to increase to $80,000 for the community, by approximately what percent would the average cost of water increase for each household in Community Z ?
a. 70% b. 13% c. 7% d. 5% e. 1.3%
OA: c
My approach: Increase in cost of water for community= $5,000
Average cost of water increase for each household= 5,000/120,000=1/24 ~ 4%
Where am I going wrong in understanding the question?
