A store that sells skis buys them from a manufacturer at a wholesale price of $63. The store’s markup rate is 50%. a. What price
Reptile [31]

a. The store charges $94.5 for the skis

b. 150% of the original price is the final price

Step-by-step explanation:

The given is:

  • A store that sells skis buys them from a manufacturer at a wholesale price of $63
  • The store’s markup rate is 50%

We need to find at what price the store charges its customers for the skis and

what percent of the original price is the final price

∵ The store buys the skis at $63

∴ The cost price of the skis = $63

∵ The store’s markup rate is 50%

- Find the amount of 50% of the cost price

∵ 50% of 63 = \frac{50}{100} × 63 = 31.5

∴ the store's markup the cost of the skis by $31.5

- To find the selling price add 31.5 to the cost price

∴ The selling price of the skis = 63 + 31.5 = $94.5

a. The store charges $94.5 for the skis

To find what percent of the original price is the final price divide the final price by the original price then multiply the quotient by 100%

∵ 94.5 ÷ 63 = 1.5

∵ 1.5 × 100% = 150%

∴ The final price is 150% of the original price

b. 150% of the original price is the final price

What are the solutions to. x^2 - x - 20 = 0
nignag [31]

Step-by-step explanation:

<em>x² - x - 20 = 0</em>

<em>x²</em><em> </em><em>-</em><em> </em><em>(</em><em>5</em><em>-</em><em>4</em><em>)</em><em> </em><em>x </em><em>-</em><em> </em><em>2</em><em>0</em><em> </em><em>=</em><em> </em><em>0</em><em> </em>

<em>x²</em><em> </em><em>-</em><em> </em><em>5x </em><em>+</em><em> </em><em>4x </em><em>-</em><em>2</em><em>0</em><em> </em><em>=</em><em> </em><em>0</em>

<em>x </em><em>(</em><em> </em><em>x </em><em>-</em><em> </em><em>5</em><em>)</em><em> </em><em>+</em><em> </em><em>4</em><em> </em><em>(</em><em> </em><em>x </em><em>-</em><em> </em><em>5</em><em>)</em><em> </em><em>=</em><em> </em><em>0</em>

<em>(</em><em>x </em><em>-</em><em> </em><em>5</em><em>)</em><em> </em><em>(</em><em>x+</em><em> </em><em>4)</em><em> </em><em>=</em><em> </em><em>0</em>

<em>Either</em><em>. </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em>

<em>x </em><em>-</em><em> </em><em>5</em><em> </em><em>=</em><em> </em><em>0</em>

<em>x </em><em>=</em><em> </em><em>5</em>

<em>Or, </em>

<em>x </em><em>+</em><em> </em><em>4</em><em> </em><em>=</em><em> </em><em>0</em><em> </em>

<em>x </em><em>=</em><em> </em><em>-</em><em>4</em>
