2 people can plough a field in 6 hours. A) how long will it take 1 person to plough the field. B) how long will it take 3 people to plough the field.

A= 12 hours B= 3 hours

Step-by-step explanation:

The more people that help the shorter the hours get

step-by-step explanation:

total income = price of one ticket   *   number of tickets sold

  y                 =     4                                   x

so the equation is y=4x     with x≥0   because number of tickets sold can not be negative

thus the equation is a semi -line with an end point at

(0,0)

passing through :

x=1     y=4(1) = 4   so through (1,4)
