So sale price= normal price-dicount
sale price=100%-20%=80%
therfor
220=80%of origonal price
80%
percent means parts out of 100
80%=80/100=8/10
220=8/10of origonal price
multiply both sdies by 10
2200=8 of origoal price
divide by 8
2200/8=275

origonal price=275

Write an equation that represents the relationship.Please help!

swat32

Answer:

n = r - 2.5

Step-by-step explanation:

We have the following data:

7 4.5

8 5.5

10 7.5

12 9.5

Now, what we will do is what happens if we subtract each one:

7 - 4.5 = 2.5

8 - 5.5 = 2.5

10 - 7.5 = 2.5

12 - 9.5 = 2.5

The difference is always kept constant, therefore the equation would be:

n = r - 2.5

If p-1/p = 4 Find (p+1/p)²

DiKsa [7]

Answer:

4

Step-by-step explanation:

$\frac{p - 1}{p} = 4$

Solve for p.

The numerator. difference has to be 4 times the answer of the denomiator.

So we can say

$p - 1 = 4p$

Solve for p

$- 1 = 3p$

$p = - \frac{1}{3}$

Now plug this in for the other formula.

$( \frac{ - \frac{1}{3} +1}{ \frac{1}{3} } ) {}^{2} = 2 {}^{2} = 4$

So
