Question

A restaurant supplier receives a discount on each oven purchased. The original price of each oven is x dollars. The restaurant supplier purchases 9 ovens for a total of (9x - 180). By how much is each oven discounted?

Answer 1

Answer:

Each oven is discounted by $20.

Step-by-step explanation:

Original price of oven in dollars  = $x$

To find total cost for 9 such ovens without discount we will apply unitary method.

If 1 oven costs in dollars = $x$

Then 9 ovens will cost in dollars = $9x$

The ovens are purchased by a restaurant supplier at some discounted price.

The new price after discount in dollars = $9x-180$

We see that the total cost of 9 ovens which was originally $=9x$ has been decreased to $=9x-180$ 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 = $\frac{\ 180}{9}=\ 20$

∴ Each oven is discounted by $20.
