A store is having a sale to celebrate president's Day. Every item in the store is advertised as one fifth off the original price. If an item is marked with a sale price of $140, what was its original price? Show your work.
Answers
80% = $140
1% = $1.75
100% = $175
Answer is $175
Final answer:
The original price of an item at the store's President's Day sale, that's now reduced to $140 after a fifth off, would have been $175.
Explanation:
The subject of this question is mathematics, specifically applying percentages and fractions in context of a store sale. To solve this problem, you need to understand that a fifth off the original price means the sale price is 80% (or 4/5) of the original. If $140 is 80% of the original price, you can find the original price by dividing $140 by 0.8.
Here are the calculations:
- Divide $140 by 0.8.
Thus, the original price of the item at the President's Day sale was $175.

A cylindrical water tank is being filled with a hose. The depth of the water increases by 1/14 ft per hour. How many hours will it take for the water level in the tank to be 3/12 ft deep?
Answers
Answer: 0.25
The starting rectangle (on the left) is larger than the ending rectangle (on the right). This means the scale factor is some value between 0 and 1, not including 0 or 1 itself.
To find the scale factor, we divide corresponding sides. We divide the vertical side 1.5 of the figure on the right over its corresponding pair on the left.
So,
scale factor = (new)/(old) = 1.5/6 = 0.25
Since 0.25 = 1/4, this means that the rectangle on the right is 1/4th as small compared to the one on the right.

1 and 1/3=1+1/3=3/3+1/3=4/3
1 and 5/8=1+5/8=8/8+5/8=13/8
4 and 1/2=4+1/2=8/2+1/2=9/2
multiply them
volume=(4/3) times (13/8) times (9/2)
volume=(4 times 13 times 9)/(3 times 8 times 2)
volume=468/48
volume=39/4
volume=9 and 3/4 cubic feet
long=4 1/2 ft=(4+1/2) ft=(8+1)/2 ft=9/2 ft
wide=1 5/8 ft=(1+5/8)ft= (8+5)/8 ft=13/8 ft
tall=1 1/2 ft= (1+1/2)ft=(2+1)/2 ft=3/2 ft
Volume=9/2 ft * 13/8 ft * 3/2 ft=(9*13*3) / (2*8*2) ft=351/32 ft³
351/32 ft³=(10*32 + 31)/32 ft³=10 + 31/32 ft³=10 31/32 ft³.
Answer:351/32 ft³ or 10 31/32 ft³

What is Darius’s error?
Answers
Answer: he needs to finish factoring the 4s.
Step-by-step explanation:
4x15 is 60, so that is right, 3x5 is 15, so that’s is right, 2x2 is 4, so that is right, but he didn’t finish factoring. 1x1 is 2, so he should have 1 and 1 coming from each 2 on the tree. Hope this helps.

Answer:
y = 4
Step-by-step explanation:
2/3(9y - 15) = 14
multiply bot sides by 3
3 × 2/3(9y - 15) = 14 × 3
2(9y - 15) = 42
divide bot sides by 2
2(9y - 15)/2 = 42/2
9y - 15 = 21
add 15 to bot sides
9y -15 +15 = 21 +15
9y = 36
divide bot sides by 9
9y/9 = 36/9
y = 4

The Mulraney's home has 2,550 square feet of living space. A contractor is building an addition to their home that will increase the square footage by 8%. What will be the square footage of their home with the addition?
Answers
Answer:
The square footage will be 2754 square feet.
Step-by-step explanation:
Given,
The original living space in the home = 2,550 square feet,
Total added space = 8 % of the original space
Thus, the living space in the home or square footage of their home, after addition = The original living space + Total added space
= 2,550 + 204
= 2,754 square feet.
2550 + (2550 X 8%)
2550 + (2550 X 0.08)
2550 + 204
= 2754
