Answer:
1. 5.6%
2. 15%
3. 300 seats
4. 2.3%
Step-by-step explanation:
1. Percent error is A-E/E*100
A is actual and e is expected
376-356/356= 0.05618*100= 5.6%
2. 17-20/20=-0.15*100= 15%
3. This time we have to solve for the actual
x-250/250*100=20
x=300 seats
4. 342-350/350=-0.0228571429*100= 2.3%
