A new novel is selling for $17.95. If it is on sale at 40% off, find the amount of discount and the sale price.
A. Discount: $10.77; Sale Price: $7.18
B. Discount: $4.39; Sale Price: $13.56
C. Discount: $13.56; Sale Price: $4.39
D. Discount: $7.18; Sale Price: $10.77
Answers
Answer:
A
Step-by-step explanation:
multiply $17.95 by 40% to get the discount ($17.95 x .4), which equals $7.18.
the sale price is the initial price of the book less the discount ($17.95-$7.18), which equals $10.77.

System of equations
There are
nickels in your pocket and
dimes in your pocket
Answers
Answer:
6 nickels and 4 dimes
Step-by-step explanation:
6 times .05 is .30
4 times .10 is .40
just add them
.40 + .30 = .70
The equation should be:
.70 = .10y + .05x
I have 4 dimes and 6 nickels.
The question is ill-formatted. The following is the question.
You have a total of ten coins in your pocket, all of which are nickels and dimes. The total value of the coins is $0.70. To find nickels and dimes in your pocket, write and solve a system of linear equations. Let x represents the number of nickels and let y represent the number of dimes. Find the number of nickels and dimes.
How much is a cent?One-hundredth of a dollar is equivalent to one cent.
How much is a nickel?A nickel is worth 5 cents. That means $0.05.
How much is a dime?A dime is worth 10 cents. That means $0.10.
How to solve the question?As per the question,
conversion of the statements into mathematical equations:
"You have a total of ten coins in your possession, all of which are nickels and dimes."this statement is converted into
x+y=10"The coins have a total value of $0.70."
this statement is converted into
0.05x+0.10y=0.70
⇒x+2y=14
Subtracting the above equation from the below equation we get y=4.
And by substituting y=4 in x+y=10 we get x=6.
Hence, I have 4 dimes and 6 nickels.

A family has three children.The oldest is 4 years older than the middle,and the youngest child is 2 years younger than the middle child.The sum of the ages of the children is 26.
Answers
Answer:
The age of the youngest child = x = 6 years
The age of middle child = y = 8 years
The age of the oldest child = z = 12 years
Step-by-step explanation:
Let us represent:
The age of the youngest child = x
The age of middle child = y
The age of the oldest child = z
The sum of the ages of the children is 26.
Hence: x + y + z = 26...... Equation 1
The oldest is 4 years older than the middle
z = 4 + y
The youngest child is 2 years younger than the middle child
x = y - 2
Hence, we substitute 4 + y for z and y - 2 for x in Equation 1
x + y + z = 26...... Equation 1
y - 2 + y + 4 + y = 26
y + y + y -2 +4 = 26
3y + 2 = 26
Subtract 2 from both sides
3y + 2 - 2 = 26 - 2
3y = 26 - 2
3y = 24
y = 24/3
y = 8
Solving for x
x = y - 2
x = 8 - 2
x = 6
Solving for z
z = 4 + y
z = 4 + 8
z = 12
Therefore:
The age of the youngest child = x = 6 years
The age of middle child = y = 8 years
The age of the oldest child = z = 12 years

Range = {24, 55, 45, 77, 3, 93}
Don't forget about the curly braces.
The domain is the set of all allowed x inputs. So we simply list all the x coordinates of the points given. That's all there is to it. The range is the list of all possible y output values, so we just list the y coordinates. Toss out any duplicate y values. Sorting each set is optional because order doesn't matter in a set.
