1. Let’s figure out the costs for each section.

2. Decorations and lightning. Each room will cost $35 + $8 = $43 and there are 3 rooms: $43 \(*\) 3 = $129.

3. Food. The total amount of guests is equal to the original amount + the “+1s”: 20 + 25% \(*\) 20 = 20 + 5 = 25. Lisa spends $3 + $10 = $13 on each guest, so, the total amount will be: $13 \(*\) 25 = $325.

4. Drinks. The number of minimum bottles Lisa will need is 25 \(*\) 2 + 10% \(*\) (25 \(*\) 2) = 50 + 5 = 55. However, the bottles is sold in packs of 12, which means she needs to buy 5 cases. This costs $30 \(*\) 5 = $150.

5. Entertainment. The total cost will be: $300 + $125 \(*\) 2 = $550.

6. Cost 1 is equal to the sum of the first three sections - $129 + $325 + $150 = $604 and Cost 2 is equal to the fourth section - $550.

7. Our answer will be: Cost 1 - $604 and Cost 2 - $550.
