two friends at work at different companies, P and S. Both complanies use the number of hours that an employee's vacation hours.
astraxan [27]
We can represent each company's graph by the following equations

V = (0.04)*H...............(Company P)

V = (0.06)*H...............(Company S)

(V represents the vacation hours and H the hours worked)

If both work 2080 hours

V1 = (0.04)*(2080) = 83.2 vacation hours..............(Company P)

V2 = (0.06)*(2080) = 124.8 vacation hours ..............(Company S)

124.8 - 83.2 = 41.6 hours

The friend at company S will have about 42 more vacation hours that the friend at company P
