To calculate the trade discount on the purchase, you need to follow these steps:

Step 1: Convert the trade discounts to decimals.
- The first trade discount is 30%, which is 0.30 in decimal.
- The second trade discount is 20%, which is 0.20 in decimal.
- The third trade discount is 15%, which is 0.15 in decimal.

Step 2: Calculate the net cost of each trade discount.
- The first trade discount is 30% of the list price, so the net cost is 100% - 30% = 70% of the list price.
- The second trade discount is 20% of the net cost after the first discount, so the net cost is 80% of 70% of the list price.
- The third trade discount is 15% of the net cost after the second discount, so the net cost is 85% of 80% of 70% of the list price.

Step 3: Calculate the trade discount on the purchase.
- To find the trade discount on the purchase, subtract the net cost from the list price.

Now let's calculate the trade discount on the purchase:

Step 1: Convert trade discounts to decimals.
- The first trade discount is 30%, so the decimal is 0.30.
- The second trade discount is 20%, so the decimal is 0.20.
- The third trade discount is 15%, so the decimal is 0.15.

Step 2: Calculate the net cost of each trade discount.
- Net cost after the first discount = 70% of the list price.
Net cost after the second discount = 80% of (70% of the list price).
Net cost after the third discount = 85% of (80% of (70% of the list price)).

Step 3: Calculate the trade discount on the purchase.
- Trade discount on the purchase = list price - net cost after the third discount.

Please provide the list price of the equipment at the amusement park.
