Question

At the city museum, child admission is 
$5.80
 and adult admission is 
$9.10
 . On Wednesday, 
155
 tickets were sold for a total sales of 
$1083.80
 . How many child tickets were sold that day?

igreen · Answer

We can make a system of equations.

5.80x + 9.10y = 1083.80
x + y = 155

Where 'x' is the number of child tickets and 'y' is the number of adult tickets.

igreen · Answer

x + y = 155

Subtract 'x' to both sides:

y = -x + 155

Plug in '-x + 155' for 'y' in the first equation:

5.80x + 9.10y = 1083.80

5.80x + 9.10(-x + 155) = 1083.80

Simplify & solve for 'x'
