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
∴ Discount on 1 oven =
∴ Each oven is discounted by $20.
When multiplying exponential expressions 7^a and 7^b, you add up the exponents over the same base of 7. This works because the two bases are both 7
So, 7^a*7^b = 7^(a+b) is the answer
Notes:
1) I used the asterisk symbol instead of the 'x' to mean multiply. This is done so we don't confuse the 'x' with a variable.
2) Parenthesis are needed to indicate that all of the "a+b" is the exponent of 7
