<u>ANSWER</u>
<u>EXPLANATION</u>
To find the value of a function, f(x) at a given value x=a, we plug in x=a into f(x) to obtain f(a) in simplified form.
The first function is
To find f(7), we substitute x=7, into the function.
The second function is
To find f(4), we replace x with 4 to obtain,
Y = 3x/4 - 1
Taking (-1-2)/(0-4) gives the slope of the line to be 3/4. Substituting x = 0 gives the y-intercept as -1.

He worked 43 hours to earn Rs. 23250
His basic pay is Rs. 18000 for a basic 36 hours a week. His salary is
Rs. 23250. This proves that he has worked extra time. So the amount earned in the extra hours equals Rs. 23250 - Rs. 18000 = Rs.5250.
Amount per hour earned in basic pay = 18000/36 = Rs.500 a hour.
∴ Amount per hour earned in extra hours = 1.5 x 500 = 750 per hour.
So number of hours he worked in extra time = Rs.5250/750 = 7 hours.
Thus total number of hours = 36 + 7 = 43 hours.
