Question 252313
At a Forest Service Youth Camp, many of the workers ate some meals away from the base camp. 
In the dining hall at the base camp, 5% of the workers had breakfast only, 
3% had lunch only, 
and 2% had supper only. Just 10% of the workers had all three meals in camp. There were 5000 meals served at the base camp dining hall. No worker missed all three meals. How many workers were assigned to the camp?
-----------------------------------
Let x be the # of workers assigned to the camp.
----
Equation:

0.05x + 0.03x + 0.02x + 0.10x = 5000

0.20x = 5000
x = 25000 (# of workers assigned to the camp)
