Let us assume the original price of the shirt = x
Let us assume the sale price of the shirt = y
20x/100 = y
x/5 = y
x = 5y
Now the second equation that we get is
x = y + 5
5y - y = 5
4y = 5
y = 5/4
Now putting the value of y in the first equation we get
x = 5y
= 5 (5/4)
= 25/4
= 6 1/4
Then we can say that the original price of the shirt was 6 1/4. The main trick of this problem lies in the words that have been used in the question. It is important to understand the question first before starting to solve the problem.
Answer:
![{3x}^{2} - 4x + 10 = 0](https://tex.z-dn.net/?f=%7B3x%7D%5E%7B2%7D%20%20%20-%204x%20%2B%2010%20%3D%200)
Step-by-step explanation:
![3(x - 2) {}^{2} + 6 \\ 3 \times x {}^{2} - 4x + {2}^{2} + 6 \\ 3x {}^{2} - 4x + 4 + 6 \\ {3x}^{2} - 4x + 10 = 0](https://tex.z-dn.net/?f=3%28x%20-%202%29%20%7B%7D%5E%7B2%7D%20%20%2B%206%20%5C%5C%20%203%20%5Ctimes%20x%20%7B%7D%5E%7B2%7D%20%20-%204x%20%2B%20%20%7B2%7D%5E%7B2%7D%20%20%2B%206%20%5C%5C%203x%20%7B%7D%5E%7B2%7D%20-%204x%20%2B%204%20%2B%206%20%5C%5C%20%20%7B3x%7D%5E%7B2%7D%20%20%20-%204x%20%2B%2010%20%3D%200)
Answer:
the person earned one summer = $3,600
We have to show the amount in fraction that Paula spent during the following semester,
they spent for tuition = $2,500 = × 100
=0.6944 × 100
= 69.44%
they spent for rent = $650 = × 100
= 0.1806 × 100
= 18.06%
they spent for food = $430 = × 100
=0.1194 × 100
= 11.94%
they Spent in tuition, rent and food = 2,500 + 650 + 430 = $3580
Now they spent in miscellaneous expenses = 3600 - 3580 = $20.00 × 100
= 0.056 × 100
= 0.56%
For you to drive 37 miles at $40 a mile it’ll be $1480. 60+(37•40)=$1540
Answer:
For thickness

For thickness
, amount = other
For thickness
, amount = $ ![1.25\times10^{3}](https://tex.z-dn.net/?f=1.25%5Ctimes10%5E%7B3%7D)
For thickness
, amount = $ 10
For thickness
, amount = $ 137
Step-by-step explanation:
Given:
Thickness of 1 dollar note =
.
∴ Total amount in dollars = ![\frac{\textrm{Total thickness}}{\textrm{Thickness for 1 dollar}}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Ctextrm%7BTotal%20thickness%7D%7D%7B%5Ctextrm%7BThickness%20for%201%20dollar%7D%7D)
