Answer:
233
Step-by-step explanation:
3 is not a factor of 32. Therefore, x will not be a whole number. X is equal to about 10.66
First 10 days...average daily increase of 0.30 .....total increase for those 10 days is (0.30 x 10) = $ 3
next days.....average daily increase of 0.45....total is (0.45 x 10) = 4.50
last ten days...average daily increase of 0.25.....total is (0.25 x 10) = 2.50
it changed all together : 3 + 4.5 + 2.5 = + 10
It is showing an overall increase, so I guess u should buy it.
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.
