Step-by-step explanation:
Write formulas for the question.
Then use substitution.
So number of $3 tickets sold is 230. But they ask for the tickets bought in advance (i.e. the tickets sold for $2). Use substitution again.

Answer:
option A and C
Step-by-step explanation:
when playing basketball, Jan makes 4 out of every 10 shots she takes
Lets make a ratio
4 out of every 10 shots is
Divide top and bottom by 2 to simplify the fraction
The ratio of number of shots Jan makes to the number of the shots she take is 2: 5
LEt x be the number of shots Jan makes and y be the number of shots she takes.Jan makes 4 out of every 10 shots she takes

we have that
f(x)=3x-2
g(x)=4x-1
3x-2=4x-1-------------> 4x-3x=-2+1--- > x=-1
find the value of f(x) or g(x) for x=-1
f(x)=3x-2 -------> f(-1)=3*(-1)-2 ------> f(-1)=-5
the solution is the point (-1,-5)
