The manager of a store orders model railroad sets that cost $390 and sells them for $429. What is the mark-up, as a percentage?
Katarina [22]

Answer:

10%

Step-by-step explanation:

We have been given that the manager of a store orders model railroad sets that cost $390 and sells them for $429.  

We will use markup % formula for our given problem.

\text{Markup percentage}=\frac{\text{Selling price- Cost}}{\text{Cost}}\times 100

\text{Markup percentage}=\frac{429-390}{390}\times 100

\text{Markup percentage}=\frac{39}{390}\times 100

\text{Markup percentage}=\frac{1}{10}\times 100

\text{Markup percentage}=10

Therefore, markup is 10% of cost.

What are the factors of the function represented by this graph? the graph of a quadratic function y = (1/4)(x + 4)(x - 8) with a
Inga [223]

Answer:

<u>option C. (x + 4) and (x − 8)</u>

Step-by-step explanation:

A factor is one of the linear expressions of a single-variable of the polynomial.

Given: y = (1/4)(x + 4)(x - 8)

When y = 0

∴ (1/4)(x + 4)(x - 8) = 0 ⇒ multiply both sides by 4

∴ (x + 4)(x - 8) = 0

So, the factors of the function are (x+4) and (x-8)

The answer is option <u>C. (x + 4) and (x − 8)</u>
