If you need to find out how many bottles of water Dave has then at the most it would be 9 bottles
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.
We can use the points (2, 8) and (4, 12) to solve.
Slope formula: y2-y1/x2-x1
= 12-8/4-2
= 4/2
= 2
Based on the question, we need to put the equation in slope-intercept form (y = mx + b).
Let's solve for the y-intercept. (We can use the point 2, 8 to solve).
y = 2x + b
8 = 2(2) + b
8 = 4 + b
8 - 4 = 4 + b - 4
4 = b
Now, that we know what the slope and y-intercept is we can put this into the final equation.
y = 2x + 4 (third option)
Best of Luck!
The correct answer is 48%
There are 10 even numbers from 1 to 21.
That makes the probability of an even number 10 out 21.
10 / 21 x 100 = 48%
Answer: 12x + 5
Explanation:
g(x) corresponds to x, so you plug -3x into x. That equals -4(-3x) + 5. Multiply to get 12x + 5. Because you can’t add a number with a variable to a whole number, that’s your answer. Hope this helps!
