Find the price of the candy bar if it is sold with a 65% mark up
A. $1.58
B. $1.44
C. $1.30
D. $1.17

Answers

Answer:

C. $1.30

Step-by-step explanation:

Multiply 0.79 and 0.65 (65%) which is about 0.51.

Add that to 0.79.

Answer:

$ 1.30

Step-by-step explanation:

Increased price =  65% of $0.79

                          [tex]\frac{65}{100}*0.79[/tex]

                         = 0.65 * 0.79

                        = 0.5135

                         = $ 0.51

Selling price  = 0.79 + 0.51 = $ 1. 30

Answer:

[tex]Area = 40 ( 84)+ 2 *(294)[/tex]

Step-by-step explanation:

There is only one figure in the attached image and the solution (surface area) is as follows:

The shape can be sub-divided into:

1. Rectangle

Dimension: 40 by 35

2. Rectangle

Dimension: 40 by 28

3. Rectangle

Dimension: 21 by 40

4. 2 triangles

Base: 21 and Height: 28

Calculate area of each and add them up to get the surface area of the figure.

1. Rectangle

Dimension: 40 by 35

[tex]A_1 = 40 * 35[/tex]

2. Rectangle

Dimension: 40 by 28

[tex]A_2 = 40 * 28[/tex]

3. Rectangle

Dimension: 21 by 40

[tex]A_3 = 40 * 21[/tex]

4. 2 triangles

Base: 21 and Height: 28

[tex]A_4 = 2 * \frac{1}{2} * 21 * 28[/tex]

So, the area is:

[tex]Area = A_1 +...+A_4[/tex]

[tex]Area = 40 * 35 + 40 * 28 +40 * 21 + 2 * \frac{1}{2} * 21 * 28[/tex]

Factor out 40

[tex]Area = 40 ( 35 + 28 + 21 )+ 2 * \frac{1}{2} * 21 * 28[/tex]

[tex]Area = 40 ( 84)+ 2 * \frac{1}{2} * 21 * 28[/tex]

[tex]Area = 40 ( 84)+ 2 *(294)[/tex]
