Jill is picking up everyone's waterbill so she is paying $60 plus $125 (being half of the water bill) so that comes out to $185.
D=185 in this case
Ron is paying for 1/3 of the rent plus the other half of the water bill. That comes out to 1/3R+125.
A=1/3R+125
And then Jack is paying for Jill's rent as well as his own. That is 2/3 of the rent.
C=2/3R
and then the choice not used is the 'no match' option. Hope this helps :)
0=0 because first you have to rearrange the terms then distribute after you have to subtract the numbers then combine like terms and once again rearrange terms I’ll add a pic to help

I hope this helped
Answer:
The number of minutes advertisement should use is found.
x ≅ 12 mins
Step-by-step explanation:
(MISSING PART OF THE QUESTION: AVERAGE WAITING TIME = 2.5 MINUTES)
<h3 /><h3>Step 1</h3>
For such problems, we can use probability density function, in which probability is found out by taking integral of a function across an interval.
Probability Density Function is given by:
Consider the second function:
Where Average waiting time = μ = 2.5
The function f(t) becomes
<h3>Step 2</h3>
The manager wants to give free hamburgers to only 1% of her costumers, which means that probability of a costumer getting a free hamburger is 0.01
The probability that a costumer has to wait for more than x minutes is:
which is equal to 0.01
<h3>
Step 3</h3>
Solve the equation for x
Take natural log on both sides
<h3>Results</h3>
The costumer has to wait x = 11.53 mins ≅ 12 mins to get a free hamburger
