The sale price of a model railroad set is $174. If it was marked down to 25% off of the original price, what was the original price?
Answer:
$217.50
Step-by-step explanation:
I) Make an equation to find the answer:
o = s + 0.25s (original price = sale price + 25% of sale price)
II) Solve:
o = 174 + 0.25(174)
o = 217.50
If the price was 174 after the mark down of 25%, then adding 25% back will give you the answer.
174 + 25% (which is 43.5) = $217.5

Mr. Hartman, the school librarian, is ordering new keyboards and mice for all of the school's computer labs. Each keyboard costs $13.50, and each mouse costs $6.50. There are 3 computer labs in the school, and each computer lab has s computer stations. Pick all the expressions that represent how much Mr. Hartman will spend on new keyboards and mice.
Answer:
3 * 20s
Step-by-step explanation:
In order to find out how much Mr. Hartman will spend in total we first need to multiply the price of the keyboard and mouse by the number of computers in a single computer station. Once we have these products we add them together. Finally, we multiply this new value by 3 since there are a total of 3 computer stations. If we turn this into an expression it would be the following...
3 * (13.50s + 6.50s)
We can even simplify this by first adding the cost of the keyboard and mouse and then multiplying by s
3 * 20s

Can you find the midpoint of the segment with the following endpoints.
(-7,-5) and (-4,2)
9514 1404 393
Answer:
(-5.5, -1.5)
Step-by-step explanation:
The midpoint is the average of the end points:
((-7, -5) +(-4, 2))/2 = (-7-4, -5+2)/2 = (-11, -3)/2 = (-5.5, -1.5)
The midpoint of the segment is (-5.5, -1.5).
What is the height and area of the polygon?
Answer:
Below in bold.
Step-by-step explanation:
If we draw a line from top right vertex perpendicular to the bottom line we get a right triangle.
Height of this triangle = sqrt(5^2 - 3^2) = 4.
This is also the height of the polygon.
The polygon is a trapezium so:
Area of the polygon = 1/2(5 + 8) * 4
= 6/5 * 4
= 26 m^2.

Altogether, 360 schoolchildren sit down for their exams.
Five percent of them have one pen. Of the remaining 95
percent, half of them have two pens and the other half
have none. How many pens do the children have between
all of them?
HEL MEEEE
Answer:
A esta así no puedo xd ._.
Total Pens, owned by all students between all of them = 360
Percentage wise calculation of Pens
Total children = 360
Students having one pen = 95% of 360 = 18
Remaining 95% = 360 - 18 = 342
Half of remaining ie 342 = 171, have two pens
Other half of remaining ie 171 have no pens
Total pens, all children have between all of them = Summation (number of students x number of pens)
= (18 x 1) + (171 x 2) + (171 x 0)
= 18 + 342
= 360
