Assume x are Erica's classes & y are Bo's classes.
x+y=35
x=2y-13
Replacing the value of x into the first equation
2y-13+y=35
3y=35+13
y=16 classes
x=2*16-13=19 classes
Answer:
C. None of the above
Step-by-step explanation:
we know that
The number of students who signed up for different after school activities are
Cooking------------> 9 students
Chess---------------> 4 students
Photography-----> 8 students
Robotics-----------> 11 students
Total of students -----> (9+4+8+11)=32
<u><em>Verify each statement</em></u>
case A) The ratio of photography students to all is 4:1
The statement is false
Because the ratio of photography students to all is 8:32
Simplify
1:4
case B) For every 1 chess student there are a total of 16 students
The statement is false
Because the ratio of chess student to all is 4:32
Simplify
1:8
so
For every 1 chess student there are a total of 8 students
therefore
C. None of the above
