a shop keeper buys 20 kg of sugar at birr y per kg. he sells 16 kg at birr (y+3/4) per kg and the rest at (y+1) per kg. what is his profit. show the step clearly​

idk this answer sorry cant on this one.

step-by-step explanation:

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.
