Answer:
88.8%
Step-by-step explanation:
1.) 30-18= 12 which is the number of member that had an average of 84
2.)Then multiply 12 times 84 = 1008
3.) You multiply 18 by 92 which equals 1656
4.)Add 1008 and 1656 together and get 2664.
5.)Divide 2664 / 30 and you get the average of 88.8

Answer simplified - 4 square root 10
Answer:
Infinitely many solutions.
Step-by-step explanation:
12(x+3)=4(2x+9)+4x
12x+36=8x+36+4x
12x+36=12x+36
infinitely many solutions
C=0.05(125000)+500
C=6250+500
C=6750
comission is $6750
