What is the definition of "markup on selling price"?

If you don't know it - look up in your textbook or class notes.

Hello, buildman!

PFS Fitness bought a treadmill for $700.

What is the selling price of the treadmill?
Round your answer to the nearest dollar.

Recall the formula: .\(\displaystyle \text{Selling Price} \;=\;\text{Cost} + \text{Markup} \quad\Rightarrow\quad S \;=\;C + M\) .[1]

We are told that: .\(\displaystyle \text{Markup} \;=\;70\%\text{ of Selling Price} \quad\Rightarrow\quad M \:=\:0.70S\) .[2]

Substitute [2] into [1]: .\(\displaystyle S \;=\;C + 0.70S \quad\Rightarrow\quad 0.30S \;=\;C \quad\Rightarrow\quad S \;=\;\dfrac{C}{0.30} \)

We are told that \(\displaystyle \text{Cost} \:=\:700.\)

Therefore: .\(\displaystyle S \;=\;\dfrac{700}{0.30} \;=\;2333.3333... \;\approx\; 2333\) dollars.
