Let's assume the price of one pack of sugar cookies is "S" and the price of one pack of oatmeal cookies is "O".

According to the given information, Habiba sold 10 packages of sugar cookies and 2 packages of oatmeal cookies for $56. We can write this as an equation:

10S + 2O = 56   ---(1)

Ruth sold 9 packages of sugar cookies and 3 packages of oatmeal cookies for $60. We can write this as another equation:

9S + 3O = 60   ---(2)

Now we have a system of two equations with two variables. We can solve this system to find the values of S and O.

Multiplying equation (2) by 2, we get:

18S + 6O = 120   ---(3)

Subtracting equation (1) from equation (3), we eliminate the variable O:
