1435 tickets are sold to a game. Admission costs $5 for some tickets $10 for others. The total ticket sales were $11,400. How many $10 tickets were sold?

Question

linear equations

Answer 1

Let x = # $10 tickets sold

Let y = # $5 tickets sold

 

x + y = 1435

10x + 5y= 11400

 

we want to find the value of x...

from 1st equation:  y = 1435-x

 

replace y with 1435-x in 2nd equation

 

10x + 5(1435-x) = 11400

 

Now just solve for x.  Good luck.

Hope this helps.
