A trader purchased 1,000 books at the rate of $5.40 per book and spent $200 towards transportation. If he wants to earn a profit of 12.5%, at what price should he sell each book?
( with explanation )
Answers
Answer:
$6.3
Step-by-step explanation:
Cost of one book = $5.40
cost of 1000 books = 1000* Cost of one book = $5.40*1000 = $5400
Transportation cost for all the books = $200
Thus, total cost for all the books = cost of 1000 books + Transportation cost for all the books = $5400 + $200 = $5600.
Given , trader wants to earn a profit of 12.5%
thus, we find 12.5 % of total cost incurred by trader
12.5 % of total cost incurred by trader = 12.5/100 * $5600. = $700
Thus, total profit for 1000 books will be $700
we know that
selling price = cost price + profit
therefore, in the given problem
selling price for 1000 books = total cost for 1000 books + total profit
substituting the value as calculated above
selling price for 1000 books = $5600 + $700 = $6300
To find selling price for one book, lets divide LHS and RHS by 1000
selling price for 1000/100 books = $6300/1000 = $6.3
Thus, trader should sell each book at $6.3 to earn a profit of 12.5%.

A red bus and a yellow bus are both driving on the same road, in the same direction They start driving from the same place and are traveling at a constant speed. The red bust started driving 0.5 hours after the yellow bus started driving. If the red bus drives 50 miles per hour and the yellow bus drives 40 miles per hour, how many miles will each bus have to traveled when the red bus catches up to the yellow bus?
Answers
Answer:
100 miles
Step-by-step explanation:
lets find out how much the yellow bus drove before red bus started
40*0.5=20
20 miles
50x=40x+20
10x=20
x=2
they traveled for two hours until red bus caught up with yellow bus
yellow:
2*40+20=80+20=100 miles
red:
2*50=100 miles

A rectangular prism and a square pyramid were joined to form a composite figure.
A rectangular prism with a length of 9 inches, width of 9 inches, and height of 5 inches. A square pyramid with triangular sides with a base of 9 inches and height 4 inches.
[Not drawn to Scale]
What is the surface area of the figure?
261 in.2
333 in.2
405 in.2
477 in.2
Answers
Answer:
B. 333 in.2
Step-by-step explanation:
The area of the base is 81^2
lateral is 45 x 4 = 180^2 (9x5x4)
180^2 add the 72 pyramid = 252^2 + base of 81^2 = 333^2
Composite figueres i do like this as shown to you a few seconds ago.
The triangle shows us just the height
4 inches
We can see that height is smaller central isosceles height across the center base point.
We also can remember to use the length 9inches but divide by 2 and get each triangle area this way.
4 x 1/2 base = 4x 1/2 4.5 = 4 x 2.25 = 9^2 each right side triangle
9 x 8 = 72^2
we add the areas 72+ 81+lateral 180 = 333 inches^2

Maria average 81 on her first three History exams. the first score was 83. The second score was 4 less than the third score. What did she score on the second and third exam
Answers
Answer:
76 on second exam, 80 on third exam
Step-by-step explanation:
First, find the total of all 3 test scores by multiplying the average by the number of elements. 81 · 3 = 243.
The first score is 83 so 243 - 83 = 160. 160 is the other two test scores combined.
To find the other 2 scores, divide 160 by 2, which is 80.
The second score is 4 less so it will be 76. The third score is 80.

Sharon drops a rubber ball from a height of 48 feet. Every bounce sends the
ball half as high as it was before.
What is the total vertical (up and down) distance the ball has traveled, from
the moment it is dropped to the moment it hits the floor for the fourth time?
(Do not include units in your answer.)
Answers
Answer:
132
Step-by-step explanation:
48 first hit and rises 24
24 second and rises 12
12 third hit and rises 6
6 forth hit
48+24+24+12+12+6+6= 132
After the 4th hit the total distance up and down covered by the ball will be 90 feet.
Why the ball is bouncing back less and less distance upward after every drop ?
Some of the kinetic energy of the ball has been transferred by the ball to the ground after each drop also when it is in the process of going upwards force of gravity is working on the opposite direction which is downwards.
There are other factors too ask your physics teacher if you are more curious.
According to the given question
First time it has been dropped from a height of 48 feet as at every bounce it bounces back half of it's value it will go up to 24 feet repeating this process of bouncing back for the fourth time
It will be (48 + 24 + 12 + 6) = 90 feet
