A store has a markup rate of 150% on the cost of their watches. They sell each watch for $435. Calculate the amount of markup on each watch.

To calculate the amount of markup on each watch, we need to determine the cost price first. The markup rate is 150%, meaning the selling price is the cost price plus 150% of the cost price.

Let the cost price be $ C $. Then:

\[
\text{Selling price} = C + 1.5C = 2.5C
\]

Given that the selling price is $435:

\[
2.5C = 435
\]

Now, solve for $ C $:

\[
C = \frac{435}{2.5} = 174
\]

So, the cost price of each watch is $174.

Now, to find the amount of markup, subtract the cost price from the selling price:

\[
\text{Markup} = 435 - 174 = 261
\]

Thus, the amount of markup on each watch is $261.

Here are five related questions for practice:
1. What is the cost price if the selling price is $500 with a 150% markup?
2. How would the markup change if the markup rate was reduced to 100%?
3. What is the selling price if the markup rate increases to 200%?
4. How do you calculate the markup percentage if the selling price and cost price are known?
5. If a watch costs $200 and the store applies a 150% markup, what will be the selling price?

**Tip:** Always express percentages as decimals (e.g., 150% as 1.5) when solving problems involving markup rates.
