I want to say the slope of AC will be 0
Answer:
1/80 of the agency's employees have PhDs.
Step-by-step explanation:
Given that:
Total number of employees = 4000
Number of employees with bachelors degree = 1000
Fraction of employees with graduate degree = 1/4 of 1000 = 250
1/5 of the employees with graduate degrees have PhD.
Number of employees with PhDs = 1/5 of 250 = 50
Now,
Fraction of PhD employees to total employees = 
Hence,
1/80 of the agency's employees have PhDs.
The cost per adult ticket is $13 and the cost per children ticket is $8
Step-by-step explanation:
Let the cost of adult tickets be 'x'
Let the cost of children tickets be 'y'
2x + 3y = 50
2x = 50 - 3y
x = (50 - 3y) /2
3x + 4y = 71
[3(50-3y) /2 ]+ 4y = 71
(150 - 9y) /2 + 4y = 71
150 - 9y + 8y = 142
150 - y = 142
y = 150 - 142
y = 8
x = (50-3y) /2
x = (50-24) /2
x = 13
The cost per adult ticket is $13 and the cost per children ticket is $8
If I understand correctly, you went wrong because you solved for Y instead of M, like the question dictates.
