Answer:
Step-by-step explanation:
i dont even know thats hard
25.3-22.25 = 3.05
What percent of 22.25 is 3.05?
22.25x = 3.05
x = .1370786517
It's marked up 13.7%
Do you mean ^2? cause if so... B don't really need crit points to solve, the parabola has a positive slope before x =2
Call the price of the bike before mark up 'x', then we have:
x + 0.25x = 210
1.25x = 210
x = 168
Therefore, the bike cost $168 before 25% price increase.
