Answer:
<em>( About ) % 31.58</em>
Step-by-step explanation:
Consider the procedure below;
<em>Thus, solution; ( About ) % 31.58</em>
Step-by-step explanation:
Original Price = $499
100% of something is the original price. when you mark something up, you are increasing the price. when the clerk marks up merchandise by 28%, they are increasing the price by 28%.
This means that the price is original + markup = 100 + 28 = 128%
Therefore, the retail price is
499 x 128% = $638.72
Answer:
False

- The radius of the container is approximately 4.89 cm
Step-by-step explanation:
<h3>
Given </h3>
A container with:
<h3>
To find</h3>
- The radius of the container
<h3>Solution</h3>
Use the equation for total surface area of cylinder:
- S = 2πr² + 2πrh or S = 2πr(r + h)
Since we have r = h and the value of S is known, let's solve this equation:
- 2πr(r + h) = 300
- 2πr(r + r) = 300
- 2πr(2r) = 300
- 4πr² = 300
- πr² = 75
- 3.14r² = 75
- r² = 75/3.14
- r² = 23.89 (rounded)
- r = √23.89
- r = 4.89 cm (rounded)
