I’m currently working on my quadrilaterals unit (specifically with trapezoids & kites) and I need major help on a lot of the
se problems.
Here’s one of them I need help solving (an answer would be preferable, but also an explanation.):

Answer:
62.5%
Step-by-step explanation:
We can write a proportion. We know that $50 is the original value and $80 is the marked up price. We don't know the marked up percentage. Let's call it x. We write equal ratios of comparing percent and
comparing the 50 to the marked up price. We then set them equal.
We then cross multiply across the equal sign from numerator to the opposite numerator.
80(x)=50(100)
80x=5000
We divide to find x.
x=62.5
This means the bicycles are marked up 62.5% and the original value is 37.5%.
