A painting contractor
determined the average amount of time needed to paint a
house.
· When 2 painters are
used it takes 20 hours to paint the exterior of a house.
· When 6 painters are
used it takes  hours to paint the
exterior of a house.
· Let p represent the number of
painters.
· Let h represent the amount of time, in hours,
required
to paint a
house.
Which statement is true about this
relationship?
a. | The time required to paint a
house varies directly with the number of painters because
h = 10p. | b. | The time required to paint a house varies directly with the
number of painters because ph =
40. | c. | The time required to paint a house varies inversely with the
number of painters because h =
10p. | d. | The time required to paint a house varies inversely with the
number of painters because ph =
40. |
