Answer:

  1. 7-5 => 2
  2. -7+5 => -2
  3. -7-5 => -12
  4. 7-(-5) => 12

Step-by-step explanation:

Lets solve the expressions one by one

<u>1. 7-5</u>

we can see that it is simple subtraction. A smaller number is being subtracted from a large number.

So the answer is 2

<u>2. -7+5</u>

There are two numbers with different signs. When there is a number with plus and a number with minus both quantities are subtracted but the larger quantity determines the sign of the answer.

In this case, 7 is larger and has negative sign, the answer will be -2

<u>3. -7-5</u>

When there are two numbers with minus sign they are added but the answer has the minus sign with it.

So the answer will be: -12

<u>4. 7-(-5)</u>

When minus is multiplied with minus it converts to positive

So

= 7-(-5) = 7+5 = 12

Hence,

  1. 7-5 => 2
  2. -7+5 => -2
  3. -7-5 => -12
  4. 7-(-5) => 12

You have made two of the exact same necklaces that cost you a total of $15 in supplies. You have chosen to mark up the price by
tatyana61 [14]

Answer:

A) The selling price for each necklaces is $8.625

B) The profit mark in each necklaces is 15%

Step-by-step explanation:

Given as :

The total cost of two necklaces = c.p = $15

The markup percentage for the necklaces = m = 15%

Let The selling price for both necklaces = s.p

A ) <u>Now, From markup method</u>

m% = \dfrac{s.p - c.p}{c.p}

or, 15% =  \dfrac{s.p - 15}{15}

or, 15% =  \dfrac{s.p}{15} - 1

or, \dfrac{s.p}{15} = 1 + 15%

or, \dfrac{s.p}{15} = 1 +  \dfrac{15}{100}

or, \dfrac{s.p}{15} =  \dfrac{100 + 15}{100}

or,  \dfrac{s.p}{15} =  \dfrac{115}{100}

∴ s.p = \frac{15\times 115}{100}

I.e s.p = $17.25

So, selling price of two necklaces = s.p = $17.25

or, selling price of one necklaces = s.p = \dfrac{17.25}{2} = $8.625

Hence, The selling price for each necklaces is $8.625

<u>Now, Again</u>

B) ∵ The total cost of two necklaces = c.p = $15

So, The cost price of one necklaces = \dfrac{15}{2} = $7.5

∴ profit% for each necklace =  \dfrac{s.p - c.p}{c.p}

i.e profit% for each necklace =  \dfrac{8.625 - 7.5}{7.5}

Or, profit% for each necklace =  \dfrac{1.125}{7.5}

Or, profit% for each necklace = 0.15

So, The profit make in each necklaces = 15%

Hence, The profit mark in each necklaces is 15%
