The answer is (1/3). So first you need to determine the fraction of time the second person worked. Multiply (1/2)x(1/3) and you will get (1/6). All the values need to add up to 1, so you can make the equation (1/2)+(1/6)+x=1. Solve for x and you will get (1/3).

Whitepunk [10]

Answer:

Master Remodeling

Step-by-step explanation:

<em>Original question is attached</em>

<h3>Option 1</h3>

C(x) = 25x + 50
C(8) = 25*8 + 50 = $250

<h3>Option 2</h3>

As per table, the rate of change is $30 per 2 hours.
So 8 hours will cost
$190 + $30 = $220

As we see the second option is cheaper so we should hire the Master Remodeling
