Cancel out,
r<2
Let x and y be the price of the fridge and the freezer before the sale, respectively.
Since the sale offers 15% off everything, Kristianne actually paid the remaining 85%
![\dfrac{85}{100}(x+y) = \dfrac{17}{20}(x+y) = 357](https://tex.z-dn.net/?f=%5Cdfrac%7B85%7D%7B100%7D%28x%2By%29%20%3D%20%5Cdfrac%7B17%7D%7B20%7D%28x%2By%29%20%3D%20357)
We are given that the freezer costed 250 before the sale, i.e. y=250. Plug this value in the equation to get
![\dfrac{17}{20}(x+250) = 357](https://tex.z-dn.net/?f=%5Cdfrac%7B17%7D%7B20%7D%28x%2B250%29%20%3D%20357)
We can manipulate this expression to get
![\dfrac{17}{20}(x+250) = 357 \iff x+250=357\cdot\dfrac{20}{17}\iff x+250=420\iff x=170](https://tex.z-dn.net/?f=%5Cdfrac%7B17%7D%7B20%7D%28x%2B250%29%20%3D%20357%20%5Ciff%20x%2B250%3D357%5Ccdot%5Cdfrac%7B20%7D%7B17%7D%5Ciff%20x%2B250%3D420%5Ciff%20x%3D170)
