Answer:
Each oven is discounted by $20.
Step-by-step explanation:
Original price of oven in dollars = [tex]x[/tex]
To find total cost for 9 such ovens without discount we will apply unitary method.
If 1 oven costs in dollars = [tex]x[/tex]
Then 9 ovens will cost in dollars = [tex]9x[/tex]
The ovens are purchased by a restaurant supplier at some discounted price.
The new price after discount in dollars = [tex]9x-180[/tex]
We see that the total cost of 9 ovens which was originally [tex]=9x[/tex] has been decreased to [tex]=9x-180[/tex] after discount.
The decrease amount is the discount amount on 9 ovens which is = $180
To find discount offered on each oven, we will again use unitary method.
Discount on 9 ovens = $180
∴ Discount on 1 oven = [tex]\frac{\$180}{9}=\$20[/tex]
∴ Each oven is discounted by $20.
