Question

At the movie theatre, child admission is $5.10 and adult admission is $8.70 . On Tuesday, 162 tickets were sold for a total sales of $1063,80 . How many adult tickets were sold that day?

Answer 1

We have 2 equations based on the information provided.
I will use C= child tickets and A= adult tickets

\[C+A=162\]
\[C(5.10)+A(8.70)=1,063.80\]
We can then use substitution to make it so we have only A as a variable.
\[C=162-A\]
\[(162-A)(5.10)+A(8.70)=1,063.80\]
Solve for A.
\[A=66 tickets\]
