The budget for the childrens museum's annual party is $20,000 . Food accounts for 1/2 of the budget , beverages accounts for 1/5 of the budget, decorations for 1/8 ,and entertainment for 1/8 of the budget . The rest of the money will be spent on staffing the event . How much money is spent on staffing?

food = 10,000

bev = 4,000
dec = 2,500
ent = 2,500

sum = 19,000 so 1,000 is left for staff

To find out how much money is spent on staffing the event, we need to subtract the amounts spent on food, beverages, decorations, and entertainment from the total budget.

First, let's calculate the amount spent on food:
The budget for food is 1/2 of the total budget. So, we can calculate it by multiplying 1/2 by the total budget:
Food = (1/2) * $20,000 = $10,000

Next, let's calculate the amount spent on beverages:
The budget for beverages is 1/5 of the total budget. So, we can calculate it by multiplying 1/5 by the total budget:
Beverages = (1/5) * $20,000 = $4,000

Now, let's calculate the amount spent on decorations:
The budget for decorations is 1/8 of the total budget. So, we can calculate it by multiplying 1/8 by the total budget:
Decorations = (1/8) * $20,000 = $2,500

Similarly, let's calculate the amount spent on entertainment:
The budget for entertainment is 1/8 of the total budget. So, we can calculate it by multiplying 1/8 by the total budget:
Entertainment = (1/8) * $20,000 = $2,500

Now, we can find out the amount spent on staffing by subtracting the amounts spent on food, beverages, decorations, and entertainment from the total budget:
Staffing = Total budget - (Food + Beverages + Decorations + Entertainment)
Staffing = $20,000 - ($10,000 + $4,000 + $2,500 + $2,500) = $20,000 - $19,000 = $1,000

Therefore, $1,000 is spent on staffing the event.
