Question

A leaky valve on the water meter overcharges Ahmed for one Liter of water for every 2 months. The overcharges amount w varies directly with time t. Find the equation that models the variation?

Answer 1

Is this all there is to this question?

Answer 2

I myself am looking for a step by step answer!

Answer 3

do you know what mean direct variation of w and t ?

@supie any idea ?

Answer 4

@AZ any idea here ?

Answer 5

the problem states that w varies directly with t

that already tells you w = kt

to find k, we can simply divide 1 L by 2 months to get the rate of overcharge per month

then plug k back into the original equation
