a computer costs 400 dollars. Its 20 percent off with an additional 5 percent off, there's no sales tax. How much does the computer cost now?
Answers
The computer costs $304 now.
Step-by-step explanation:
Given,
Cost of computer = $400
First discount = 20%
Amount of discount = 20% of $400
Amount of discount =
Amount of discount = $80
Price after first discount = 400-80 = $320
Additional discount = 5%
Amount of additional discount = 5% of price after first discount
Amount of additional discount =
Amount of additional discount = $16
Final cost = 320-16 = $304
The computer costs $304 now.

Stock A dropped 0.67, so...
StockA= -0.67
Stock B dropped 0.60, so...
StockB= -0.60
Stock C dropped more than Stock B but not as much as Stock A, so we can write the inequality:
StockB≥StockC≥StockA
Now lets fill in the values that we know...
-0.60 ≥ StockC ≥ -0.67
So we're looking for a number in between -0.60 and -0.67...
A) -0.70 is NOT between the two numbers
B) -0.63 IS between the two numbers
C) -0.56 is NOT in between the two numbers
D) -0.48 is NOT in between the two numbers
Answer= B) -0.63

According to the concept of graphs ..
the Answer is
A.) y >= 1
Answers
If x is the number of days and y is the cost
a) y = 0x + 70 or y = $70
If there is no daily cost, then the price will always remain $70. (Blue)
There will be a horizontal line intersecting the y axis at $70.
b) y = 4x + 15
The initial cost in addition to whatever the number of days is, multiplied by $4 per day.
Day 1: (4 x 1) + 15 = $19
Day 2: (4 x 2) + 15 = $23
Day 3: (4 x 3) + 15 = $27
Day 4: (4 x 4) + 15 = $31
By now, we should be able to notice a pattern, the y value always increases by $4, after starting at y = $19
On the graph, after plotting these 4 points, we would just continue the straight line along until it spreads across the entire graph.
c) y = 6x
The total cost for all the sessions will be the number of days multiplied by the cost per day.
As it is 6 multiplied by the number of days, we must write out the 6 times table:
x = 1 2 3 4 5 6 7 8 9 10
y = 6, 12, 18, 24, 30,36, 42, 48, 54, 60 etc.
Just plot some of these co-ordinates on the line (at least three to be sure) and check that they make a straight line. They are correct if they do.
After plotting all these co-ordinates, we will get something that looks like the image attached.
This tells us that daily pay is cheaper, until 8 days have passed. After that, it gets increasingly pricier to pay per day. Deposit plus then becomes the cheapest until the 14 day mark, where it then becomes cheaper to have paid the Early pay. From then onwards, early pay would have been the best option to choose.
Daily Pay - up to and including 7 days
Deposit Plus - up to and including 13 days
Early Pay - 14 days or more.

Whole numbers are the numbers 0, 1, 2, 3, 4, 5, 6...and so on. It is easier to compare two numbers through the millions using a place value chart. This is illustrated in the Figure bellow. In that example, we have chosen two numbers:
Number one:8,472,102
Number two:8,470,443
So, by comparing these numbers we will have the following steps:
Step 1. The millions are both 8.
Step 2. The hundred thousands are both 4.
Step 3. The ten thousands are both 7.
Step 4. The one thousands digits are 2 and 0.
Stop in this step and compare the digits, so:
2 is greater than 0 or 2 > 0
Therefore, the solution is:
Number one > Number two, that is:
8,472,102 > 8,470,443
In conclusion, you need to stop in the step at which the digits are not the same and compare them. The greatest number is the one with the greatest digit.
