Answer:
Each oven is discounted by $20.
Step-by-step explanation:
Original price of oven in dollars =
To find total cost for 9 such ovens without discount we will apply unitary method.
If 1 oven costs in dollars =
Then 9 ovens will cost in dollars =
The ovens are purchased by a restaurant supplier at some discounted price.
The new price after discount in dollars =
We see that the total cost of 9 ovens which was originally has been decreased to
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
