Dylan's Bicycle Shop offers a new bicycle on sale for $259.92 after a 10% markdown. What was the cost of the bicycle to Dylan if the markup was 30% based on the cost? Round

P = Po - 0.1Po = 259.92

0.9Po = 259.92
Po = 288.80 Before 10% markdown.

P = Po + 0.3Po = 288.80
1.3Po = 288.80
Po = $222.15 = Cost to Dylan.

To find out the cost of the bicycle to Dylan before the 30% markup, we can use the given sale price and the 10% markdown.

Step 1: Calculate the original price before the markdown.
We know that the sale price is $259.92 after a 10% markdown. Let's represent the original price as "x."

The markdown amount is 10% of x, which is 0.10x. Subtracting the markdown from x will give us the sale price:

x - 0.10x = $259.92

Combining like terms:

0.90x = $259.92

Step 2: Solve the equation for x.
To isolate x, divide both sides by 0.90:

x = $259.92 / 0.90

x = $288.80

So, the original cost of the bicycle to Dylan before the 30% markup was $288.80.
