The library raised $320,100 when 400 books were sold per day.
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
Number of days book sale = 4
The library paid for advertisement each day = $25
Cost of each book (b) = $2.00.
The expression represents the amount of money the library raised at the book sale.
= 4(25) + 2b(400)
Now,
Substitute b = 400 into the expression.
= 4(25) + 2(400)(400)
= 4(25) + 320000
= 320100
Therefore,
The library raised $320,100 when 400 books were sold per day.

Maybell just purchased $2075 worth of jewelry. If she marks up her cost by 30% and sells all of the jewelry, what will be the total retail cost of all the jewelry?
Answer:
times 2075 by .30 and that's your answer
The total retail cost of all the jewelry is $2697.5
What is Percentage?To determine the quantity or percentage of something in terms of 100, use the percentage formula. Per cent simply means one in a hundred. Using the percentage formula, a number between 0 and 1 can be expressed. A number that is expressed as a fraction of 100 is what it is. It is mostly used to compare and determine ratios and is represented by the symbol %.
Given:
Maybell just purchased $2075 worth of jewelry.
Now, marks up her cost by 30% then
= 2075 x 30/100
= 622.5
Thus, the total retail cost of all the jewelry
= 2075+ 622.5
= $2697.5

Ally's Fitbit tells her she has completed 73% of her goal for number of steps taken
today. If she has taken 5,840 steps, what is Ally's goal for the day
Answer:
7416.8
Step-by-step explanation:
5,840 x 127%
Since she's 73 percent of the way there, we need to add the last 27 percent as well as put a one in front so it will work.
127%
Because this is not just 7416 steps you should consider rounding it if your teacher asks you to.
A large stockpile of used pumps contains 20% that are currently unusable and need to be repaired. A repairman is sent to the stockpile with three repair kits. He selects pumps at random and tests them one at a time. If a pump works, he goes on to the next one. If a pump doesn't work, he uses one of his repair kits on it. Suppose that it takes 10 minutes to test whether a pump works, and 20 minutes to repair a pump that does not work. The expected value and variance of the total time it takes the repairman to use up his three kits are, respectively:____.
Answer:
Expected value = 190
Variance = 4000
Step-by-step explanation:
Let X be the number of the trials until the third success of the bad pump.
This implies that X is a negative binomial distribution having θ = 20% = 0.2.
Now, if for example it will take X trials to use up the three pumps, then the total time is 10 min/trials + extra 10 minutes for the 3 bad pumps
This means the total time is written as;
T = 10X + (10 + 10 + 20)
T = 10X + 40
Mean which is also expected value of X is;
μ_x = 3/0.2 = 15
Variance of X is; σ²_x = 40
Thus;
Mean of T will be;
μ_T = 10μ_x + 40
μ_T = 10(15) + 40
μ_T = 190
Also, variance of T will be;
σ²_T = 10²•σ²_x
σ²_T = 100 × 40
σ²_T = 4000

What is an ordered pair?An ordered pair is made up of the ordinate and the abscissa of the x coordinate, with two values given in parenthesis in a certain sequence.
Pair in Order = (x, y)
x is the abscissa, the distance measure of a point from the primary axis x
y is the ordinate, the distance measure of a point from the secondary axis y
Given, The point is on the x-axis and 17 units to the left of the y-axis.
Now, the value of y at the y-axis is 0 and the point is 17 units left to it so it should be - 17.
So, the coordinate points are (- 17, 0).
