Step 1:
Cost * Markup= $ Markup
=$20 * 15%
=20 * 0.15
=$3.00 markup

Step 2:
Cost + $ Markup= Selling Price
$20 + $3 = $23.00

Selling Price= $23.00

Hope this helped :)

Elle and heather drew floor models of there living rooms.Elles model respresented 20 feet by 15 feet.Heathers model respresented

ludmilkaskok [199]

Answer:

Heather's model represents the greater area.
$24\ ft^2$ greater.

Step-by-step explanation:

The formula for calculate the area of a rectangle is:

$A=lw$

Where "l" is the lenght of the rectangle and "w" is the width.

The formula for calculate the area of a square is:

$A=s^2$

Where "s" is the side lenght.

In this case, knowing that Elle's model represented 20 feet by 15 feet, we can say that:

$l=20\ ft\\w=15\ ft$

Therefore, substituting these values into the formula $A=lw$ , we get that the area is:

$A_1=(20ft)(15ft)=300\ ft^2$

Since Heather's model represented 18 ft by 18 feet, we can identify that:

$s=18ft$

Substituting this value into $A=s^2$ , we get this area:

$A_2=(18ft)^2=324\ ft^2$

Notice that Heather's model represents the greater area.

To calculate how much greater it is, subtract the areas. Then:

$324\ ft^2-300\ ft^2=24\ ft^2$

Rework problem 7 from section 3.4 of your text, involving the selection of a colored ball from one of three bowls. Assume that y

allochka39001 [22]

Answer:

Question (1): 1/2 = 0.5

Question (2): 1/6 ≈ 0. 17

Explanation:

1. Arrange the information of the balls contained in the bowls in a table:

Bowl X Bowl Y Bowl Z Total

Red balls 2 2 1 5

White balls 2 1 3 6

Blue balls 3 1 2 6

==============================

Totals 7 4 6 17

2. To answer each question use the basic definition of probabilities

Probability = # of favorable events / # of possible events

3. Question (1) If the ball is blue, what is the probability that it was drawn from bowl X?

Number of total blue balls: 6

Number of blue balls in the bowl X: 3

Probability that a ball that is blue was drawn from the bowl X: P (b/X)

P (b/X) = number of blue balls in the bowl X / total number of blue balls = 3 / 6 = 1/2 = 0.5

4. Question (2) If the ball is either blue or white, what is the probability that it was drawn from bowl Y?

Number of total blue and white balls: 6 + 6 = 12

Number of blue balls and white balls in the bowl Y: 1 + 1 = 2

Probability that a ball that is either blue or white was drawn from the bowl Y: P (b or w / Y)

P (b or w /Y) = number of blue balls and white balls in the bowl Y / total number of blue balls and white balls = 2 / 12 = 1/6 ≈ 0.17

Is x = -3 a solution to 5x + 7 = 4

SVEN [57.7K]

So, 5 x (-3) + 7 = -15 + 7 = - 8 , but not 4;
Then, -3 is not a solution to 5x + 7 = 4;
