Cody, the owner of an e-commerce site, buys emerald pendants for $400 and then sells them
Trava [24]

Answer:

The marked up percentage is 112.5%

Step-by-step explanation:

The cost price of the emerald pendant = $400

The selling price of the emerald pendant = $840

Now, the Mark up Price  = Selling Price - Cost Price

                                          = $840  - $400 = $450

Also, \textrm{Percentage of Mark up Price}  = \frac{\textrm{the Marked up price}}{\textrm{The Cost Price}}  \times 100

= \frac{450}{400}  \times 100 = 112.5

⇒  Percentage of Mark up Price =  112.5%

Hence, the marked up percentage is 112.5%

(5,12)and (2,6) rate of change?<br> Initial value?<br> HURRY i NEED this done.
Otrada [13]

Answer:

Part 1) The rate of change is 2

Part 2) The initial value is 2

Step-by-step explanation:

we know that

The linear equation in slope intercept form is equal to

y=mx+b

where

m is the slope or rate of change

b is the y-intercept or initial value

step 1

Find the slope or rate of change

The formula to calculate the slope between two points is equal to

m=\frac{y2-y1}{x2-x1}

we have the points

(5,12)and (2,6)

substitute the values in the formula

m=\frac{6-12}{2-5}

m=\frac{-6}{-3}

m=2

therefore

The rate of change is 2

step 2

Find the initial value

we have

m=2

point\ (2,6)

substitute in the equation y=mx+b

6=2(2)+b

solve for b

6=4+b

b=2 ---> initial value

The linear equation is equal to

y=2x+2

The y-intercept or initial value is 2
