Answer:
a)10$
Step-by-step explanation:
Given the rate of water flow is given by:
r(t)=85e^(-0.04t)
thus the amount of water flow in the first hour when t=1, will be:
r(1)=85e^(-0.04*1)
=81.667
thus the amount of water that flowed out will be:
85-81.667
=3.333 liters
The final bill after applying discount will be $80.92

Worth of items bought by Sara = $124.50
Discount = 35%
Amount of discount = 35% of worth of items
Amount of discount = 
Amount of discount = 
Amount of discount = $43.575 = $43.58
Final bill = Worth of items - Amount of discount
Final bill = 124.50 - 43.58 = $80.92
The final bill after applying discount will be $80.92
