Comparing linear functions word problem

Natsumi and Ilya paint walls for a living. For each paint job, they each paint at a constant speed and then take some time to clean up.
The time it takes Natsumi to finish painting (in hours) as a function of the total area to paint (in square meters) is given by the following function:
T(A)=0.5+0.06AT(A) = 0.5+0.06A
The time it takes Ilya to finish painting (in hours) as a function of the total area to paint (in square meters) is given by the following table of values:
Area\text{Area} (square meters)Time\text{Time} (hours)
303022
