Sale price of a new refrigerator is $262.5 and Sale price of new range of top = $225 when purchased together. 
Solution: 
Given that 
Mackenzie purchased a new refrigerator for $350 
Mackenzie purchased a new range of top for $300 
The store was offering a deal of 25% if both were purchased at the same time. 
Need to determine sale price of these two items 
Assuming that these two items are purchased at the same time , there will be 25% deal 
So sale piece of a new refrigerator of $350 = $350 – 25% of $350 = 350 – 0.25 x 350 = 350 – 87.5 = $262.5 
And Sale price of new range of top = $300 = $300 – 25% of $300 = 300 – 0.25 x 300 = 300 – 75 = $225 
Hence sale price of a new refrigerator is $262.5 and Sale price of new range of top = $225 when purchased together.
