The answer should be A because point slope form is y-y1=m(x-x1)....M is the starting point and its -56 and y1(-4) is the y value of the coordinate point and x1(8) is the x value of the coordinate point. it changes to y+4 because two negative signs make a positive(y--4)

How do you solve this: $32 earrings marked up 80 percent
Taya2010 [7]
Formula for markup
sales price = original price × ( 1 + rate )

So in this case it would be...
sp = $32 × ( 1 + .80 ) 
         $32 × ( 1.80 )
sp = $57.60

formula for discount ( if you need it ) 
sales price = original price × ( 1 - rate )
Just remember that the rate is the percentage ( to convert to a percentage to a decimal just move the decimal two places to the left )

If 75 percent of the employees of a certain company take a winter vacation, 40 percent take a winter and a summer vacation, and
KATRIN_1 [288]

Answer:

The answer is option A : 5%

Step-by-step explanation:

We have the following information in percentage:

Employees taking winter vacation= 75

Employees taking both winter and summer vacation= 40

Employees taking none vacation = 20

We can assume the situation as following:

Winter + Summer - Both + Neither = 100

We get;

75 + Summer - 40 + 20 = 100

So, summer = 45

45 people take vacations in summer. But 40 of them take vacation in winters too.

So, people taking vacations in summer but not winter means summer only.

This is : 45-40=5%

Therefore, the answer is option A : 5%
