Step-by-step explanation:
We can create a proportion to find the markup from original price to the marked up price. A proportion is an equation where two ratios are set equal to each other. We create two fractions using the prices and percents. It is marked up by 20% so we pay 120% of $50.
![\frac{120}{100} =\frac{x}{50}](https://tex.z-dn.net/?f=%5Cfrac%7B120%7D%7B100%7D%20%3D%5Cfrac%7Bx%7D%7B50%7D)
We begin solving by cross multiplying numerator to denominator of each fraction.
![120(50)=100(x)\\6000=100x\\\frac{6000}{100}=\frac{100x}{100} \\60=x](https://tex.z-dn.net/?f=120%2850%29%3D100%28x%29%5C%5C6000%3D100x%5C%5C%5Cfrac%7B6000%7D%7B100%7D%3D%5Cfrac%7B100x%7D%7B100%7D%20%20%5C%5C60%3Dx)
