Kristianne buys a fridge and a freezer in a sale The sale offers 15% off everything and she pays a total of $ 357 Before the sale, the freezer cost $ 250 . What was the cost of the fridge before the sale?'

Step 1: Determine the total cost of the items after the discount. We know that Kristianne paid $357 after a 15% discount.

Step 2: To find the original price before the discount, we need to calculate the total cost before the discount. Since the discount is 15%, this means that Kristianne paid 85% (100% - 15%) of the total original price. So, we can set up the equation: 0.85 * (fridge price + freezer price) = $357

Step 3: We know the original price of the freezer was $250. Substitute this into the equation: 0.85 * (fridge price +$250) = $357

Step 4: Solve the equation for the fridge price. First, distribute the 0.85 to both terms in the parentheses: 0.85 * fridge price + 0.85 * $250 =$357

Step 5: Simplify the equation: 0.85 * fridge price + $212.5 =$357

Step 6: Subtract $212.5 from both sides of the equation to isolate the term with the fridge price: 0.85 * fridge price =$144.5

Step 7: Divide both sides of the equation by 0.85 to solve for the fridge price: fridge price = $144.5 / 0.85

Step 8: Calculate the result: fridge price = $170

So, the fridge cost $170 before the sale.
