Answer:
(0,3) ; (2,3) ; (0,0) ; (3.5,0)
Step-by-step explanation:
Firstly, we have to plot all the giving inequalities as constraints
Not to forget, f(x) can be written as y
Kindly find the plot as an attachment
Upon plotting, we have the following vertices;
(0,3) ; (2,3) ; (0,0) ; (3.5,0)
10 people who build at the same rate can frame a house in 6 days. That means it will take one person days to finish the house.
Which means that it will take 4 people days to finish the house.
So, the fractional part of the house 4 people can frame in 3 days will be
Thus, Option D is the correct answer.
