Answer:
81000 people went to Bonnaroo.
192000 people went to Lollapalooza.
Step-by-step explanation:
Given:
Total number of people attending festivals, ![N=273000](https://tex.z-dn.net/?f=N%3D273000)
Number of people attending Lollapalooza is 30,000 more than twice the people attending Bonnaroo.
Unknown:
Number of people attending Lollapalooza and Bonnaroo.
Let the number of people attending Bonnaroo be
.
Therefore, the number of people attending Lollapalooza is equal to ![30000+2x](https://tex.z-dn.net/?f=30000%2B2x)
Evaluate:
Sum of people attending Bonnaroo and Lollapalooza is equal to the total number of people attending the festivals. So,
![x+30000+2x=N\\3x+30000=273000\\3x=273000-30000\\3x=243000\\x=\frac{243000}{3}=81000](https://tex.z-dn.net/?f=x%2B30000%2B2x%3DN%5C%5C3x%2B30000%3D273000%5C%5C3x%3D273000-30000%5C%5C3x%3D243000%5C%5Cx%3D%5Cfrac%7B243000%7D%7B3%7D%3D81000)
Substitute and Solve:
Now, we have,
.
Substitute 81000 for
and solve for the number of people attending both the festivals. This gives,
Number of people attending Bonnaroo = ![x=81000](https://tex.z-dn.net/?f=x%3D81000)
Number of people attending Lollapalooza = ![30000+2x=30000+2(81000)=30000+162000=192000](https://tex.z-dn.net/?f=30000%2B2x%3D30000%2B2%2881000%29%3D30000%2B162000%3D192000)
Therefore, 81000 people went to Bonnaroo and 192000 people went to Lollapalooza.
