The initial value of the given function is $5 at time = 0.
This means that Yookyung takes $5 when she works zero hours.
In other words, she takes $5 even before she begins working.
Comparing this to the given choices, we will find that the best choice is:
<span>C. Yookyung charges $5 before she begins babysitting.</span>
KH = 3(x + 2) + <span>3x - 4
KH = 3x + 6 + 3x - 4
KH = 6x + 2 = 44
6x = 42
x = 7
HJ = 3(x + 2)
HJ = 3(7 + 2)
HJ = 27</span>
A=pi r^2
<span>then use your rate of $4.60/m^2 and multiply that by your area. </span>
<span>A = 3.14 (.8^2) </span>
<span>Cost = 2.01 m^2 $4.60/m^2 = $9.24
So your answer would be B</span>
