Profit made through $ paintings is
Profit made through $ paintings is
So,total profit is given by
It is given that total profit is $
So, ..(i)
Given that the total number of prints is
So, ..(ii)
using (i) and (ii),
Kx-3y=k
y=4x+1 ( we will put it in 1st equation )
kx - 3 (4x+1)=k
kx - 12 x - 3 =k
kx - 12 x = k+3
x(k-12) = k+3
x=
Also y=
We can not divide with zero.
k-12=0
k=12
For k= 12 equations have no solutions.
y=4x+1 ( we will put it in 1st equation )

kx - 12 x - 3 =k
kx - 12 x = k+3
x(k-12) = k+3
x=
Also y=
We can not divide with zero.
k-12=0
k=12
For k= 12 equations have no solutions.
