Answer:
The result is the same.
Step-by-step explanation:
I think your question is missed of key information, allow me to add in and hope it will fit the original one.
Please have a look at the attached photo.
My answer:
Given the information:
- square 12 inches wide
- 3-inch diameter cookies are cut => its radius is: 1.5 inches
Hence we can find some information:
- The area of the square is:
square inches - The area of a cookies is:
π = 3.14*
= 7.065 square inches - The total number of 3-inch cookies are: 4*4 =16
=> The total area of the cookies is: 16* 7.065 = 113.04 square inches
=> how much cookie dough is "wasted" when 3-inch cookies are cut:
= The area of the square - The total area of the cookies
= 144 - 113.04 = 30.96 square inches
If the diameter is increased to 4 inches => its radius: 2 inches, we have:
- The area of a cookies is: π =
square inches - The total number of 3-inch cookies are: 3*3 =9
=> The total area of the cookies is: 9* 12.56 = 113.04 square inches
=> how much cookie dough is "wasted" when 4-inch cookies are cut:
= The area of the square - The total area of the cookies
= 144 - 113.04 = 30.96 square inches
The result is the same.
First, start by transferring a liter to a gallon. 3.78 liters in 1 gallon.
This means they pay 1.65*3.78=6.24 euros per gallon of gasoline. If the conversion is 1 us dollar = .76 euros, set up a proportion where x$=6.24euros.... .76x=6.24.... x=$8.21
Next, do the reverse. One liter is .26 gallons, meaning we pay 3.90*.26=$1.01 for a liter of gas. Convert this back into euros by multiplying it by .76... 0.77 Euros
A
It should be the 90 pack container. You should see the difference in buying that as opposed to the 2 smaller containers. Usually stores make you think that way, but sometimes they pull a fast one and make the lower content container the better buy. You should ALWAYS shop with a calculator. I'll give you an example. Suppose the packs are listed as below
Number packs Price Unit Price
30 pack 8.99 30 cents rounded
60 pack 17.00 28.33
90 pack 23.00 25.55
This one worked as it should. It's fair to the consumer and it's actually fair to the merchant and the manufacturer.
B
The answer to B is what I actually did to get the answers for A
20 5.49
Unit Cost = Total Cost divided by number in the container.
Unit Cost = 5.49/20 = 0.2745 dollars or 27 cents.
C
Done the same way as B
Unit Cost = 10.97/ 60 = 0.1828 dollars which rounds to 28 cents.
D
Unit Cost = 18.95/90 = .211 dollars = 21 cents. This is an example of when the merchant is trying to persuade you to buy something that is not the best buy. And they do that.
E
I will let you answer this yourself. Education is meant to make you wise in what you do. This question is something you should become familiar with. Don't just buy something. Unit cost it. It takes longer but you are saving money and you'd be surprised what you save at the end of a year.
