Elodia [21]
Hello! So $10,000 is the annual budget. 50% of the budget is spent on food, 25% of it is spent on beverages, 10% is spent on decorations, and the remaining 15% is spent on staff for the party. That's because 50 + 25 + 10 is 85. 100 - 85 is 15. Let's multiply the budget by 15% to find the amount spent on staff. 10,000 * 15% (0.15) is 1,500. There. $1,500 were spent on staff for the party.
