Answer:
the customer is wrong
Step-by-step explanation:
when he raised then 50 % they became $150 and then If you do the work 50% of $150 is $75 .
100+%50
150
150-%50
75
The customer is wrong because the new price of the shoe is $75 and not $100.
When the shop owner raises the price of a $100 pair of shoes by 50%, then the new price will be:
= $100 + (50% × $100)
= $100 + $50
= $150
Then, the owner reduces the price by 50%, then the new price will be:
= $150 - (50% × $150)
= $150 - $75
= $75
Therefore, the new price is $75.

in a study of 300 students under 25 years old, 21have not yet learned to drive. What percentage can drive?
Answer:
93%
Step-by-step explanation:
From the question given above, the following data were obtained:
Total number of student = 300
Number of student that can not drive = 21
Percentage of student that can drive =.?
Next, we shall determine the number of student that can drive. This can be obtained as follow:
Total number of student = 300
Number of student that can not drive = 21
Number of student that can drive =?
Number of student that can drive = (Total number of student) – (Number of student that can not drive)
Number of student that can drive = 300 – 21
Number of student that can drive = 279
Finally, we shall determine the percentage of student that can drive as illustrated below:
Total number of student = 300
Number of student that can drive = 279
Percentage of student that can drive =?
Percentage of student that can drive =
279/300 × 100
= 93%
Thus, 93% of the student can drive.
Liz is taking guitar lessons and practices every night. Yesterday, she played a total of 40 chords in 8 minutes. Today she will play chords for 5 minutes. If she plays at the same rate, how many chords will Liz play today?
Answer:the answer is 25
Step-by-step explanation:
40 divided by 8 = (chords played per minute)
5 times (chords played per minute and you get your answer
Liz will play a total of 25 chords in 5 minutes today which is determined by the ratio.
What is Ratio?The ratio is defined as a relationship between two quantities, it is expressed as one divided by the other.
We have been given that Liz played a total of 40 chords in 8 minutes.
Let's assume she plays a total of x chords in 5 minutes.
According to the given question, we can write the ratio as:
40 chords : 8 minutes = x chords : 5 minutes
⇒ 40 / 8 = x / 5
Apply the cross-multiplication operation,
⇒ 8x = 40 × 5
Apply the multiplication operation,
⇒ 8x = 200
⇒ x = 200/8
Apply the division operation to get the answer
⇒ x = 25
Therefore, she will play a total of 25 chords in 5 minutes.

What is the answer for 3(x+5)=5x+7
Answer:
4 = x
Step-by-step explanation:
First, distribute the 3 to the x and 5.
3x + 15 = 5x + 7
Now, subtract 3x from both sides and 7 from both sides.
8 = 2x
Now, divide by 2 on both sides.
4 = x

now, is it fine..
whats the y-intercept of y= 1/3 x-1y
Answer:
(0, 0)
Reasoning:
Y-intercept means set x to 0 and solve, therefore;
[tex]y=1/3(0) -1y[/tex]
[tex]y=0-1y[/tex]
[tex]2y=0[/tex]
[tex]y=0/2=0[/tex]
Thus, the y-intercept is (0,0)

10 .find the partial sum S10 of the arithmetic series with a1 = 4, d = 5.
Answer:
S10 = 320
Step-by-step explanation:
The formula for calculating the sum of the nth term of an AP is expressed as
Sn = n/2(2a+(n-1)d))
Given
a = 4
d = 5
n = 10
S10 =10/2{2(5)+(10-1)5}
S10 =5{10+9(6)}
S10 =5{10+54}
S10 = 5(64)
S10 = 320
Hence the sum of the first ten terms of the sequence is 320
Absolute value of -4 1/2
Answer: 4 1/2
Step-by-step explanation:
The absolute value of a given number is [tex]4\frac{1}{2}[/tex].
What is an absolute value?The absolute value of a number is defined as its magnitude irrespective of the sign of the number. To find the absolute value of a real number, we consider only the number and remove the sign. It can only be a non-negative value.
The given number is [tex]-4\frac{1}{2}[/tex].
So, absolute value of a number is
|[tex]-4\frac{1}{2}[/tex]|= [tex]4\frac{1}{2}[/tex]
Hence, the absolute value of a given number is [tex]4\frac{1}{2}[/tex].

Among all pairs of numbers with a sum of 105 , find the pair whose product is maximum. Write your answers as fractions reduced to lowest terms.
Answer: Hence Pair( x, y) = [ 105/2, 105/2]
Step-by-step explanation:
Given that;
Among all pairs of numbers with a sum of 105;
the pair whose product is maximum = ?
so let pairs of numbers with a sum of 105 be x and y respectively
x + y = 105
let y = 105 - x
now
product = xy = x( 105 - x ) = 105x - x²
now
p(x) = 105x - x²
for maximum value of p
dp/dx =0
⇒ dp/dx = 105 - 2x = 0
2x = 105
x = 105/2
y + x = 105
y = 105 - x
y = 105 - 105/2 = 105/2
Hence Pair( x, y) = [ 105/2, 105/2]

Change
= $20 - total price of the items bought
Total price of bottled water
= 4($2.75)
= $11
Total price of fruit punch
= 5($1.35)
= $6.75
Change
= $20 -($11 +$6.75)
= $20 -$17.75
