$1186.10
. How many child tickets were sold that day?

Number of child tickets:

Answer 1

(i guess you mean child admissions tickets ?)lets say child tickets = x
adult tickets = y
First, write the cost equation
$5.30 for child tickets so 5.30x
and $8.40 for adult -> 8.40y
and *tickets were sold for the total sales of
$1186.10*
\[5.30x+8.40y=1186.10\]
first equation
2nd equation will represent the number of tickets were sold
x+y=177
that is the 2nd equation.
now its up to you..how you gonna solve for x ?
substitution ?
elimination?(which is not the best for this question )
or graphing
