Answer:
The total number of bugs in the collection is 36
Step-by-step explanation:
Let
x -----> the number of bugs that you find out
y ----> the number of bugs that the classmate find out
we know that
\(\frac{x}{y+x} =\frac{5}{9}\) -----> equation A
\(x=y+4\) ----> equation B
Solve the system by graphing
Remember that the solution is the intersection point both graphs
The solution is the point (20,16)
The total number of bugs in the collection is
\((20+16)=36\ bugs\)
