QR is the median of the trapezoid, so its length is the average of the top and bottom bases. Write that. Say (length of QR)=1/2 of (length of the top + length of the bottom). That gives you a nice simple equation that you can easily solve for 'x'.
The number of months overcharged for 1 gallon of leaky water = 1 1/3
= 4/3
Let us assume the quantity of water overcharged = w
Let us assume the time in months = t
Then, the equation modelling this direct variation is
w = (3/4)t
When w = 5, then
5 = (3/4) * t
20 = 3t
t = 20/3
= 6 2/3
From the above deduction, we can conclude that the first option or option "A" is the correct option. I hope the answer helps you.
