Question

Rendering math...A jug has a maximum capacity of 3 liters. It’s filled to 95% of its capacity, and then poured out at a rate of 40 mL/s. Which of the following expressions models the volume remaining in the jug, in liters, after x seconds?

Answer 1

95% of 3 is 2.85 liters

1 ml = 1000 liters so divide the amount it’s emptied by 1000

40/1000 ml/s

Multiply the emptied rate by x ( number of seconds) and subtract that from starting amount:

W(x) = 2.85 - (40/1000)x
