Answer:
Step-by-step explanation:
6x - 6 = 7x - 8
-x = -2
x = 2
CJ= 6(2) - 6 = 12 - 6 = 6
JT= 7(2) - 8 = 14 - 8 = 6
6 + 6 = 12 for CT
Number of females = f
Total number of people in audience = n
0.4n = f
f + (f+ 100) = n
2f + 100 = n
Find n:
f = 0.4n --> Replace f with 0.4n in the equation 2f +100 = n
2(0.4n) + 100 = n --> Multiply out the brackets
0.8n + 100 = n --> Subtract 0.8n from both sides
100 = 0.2n --> To get n, multiply both sides by 5
n = 500
There were 500 people in the audience.
