Hallie just graduated and got a great job as a graphic designer in San Francisco with a starting salary of $55,205 per year. After looking at the cost of apartments in SF she decided to consider a crazy plan she read about online: living in Las Vegas and commuting to San Francisco for her new job. She decides to ask her boss how many days she will need to work in the office and how many days she can work from home.
Then she does some research and finds the following costs:
Average rent per month: San Francisco $2965, Las Vegas $610.
Average cost of transportation per day: San Francisco $7, Las Vegas $155.

Let x = the number of adult tickets you sold.
Naturally, the number of child tickets you sold would be 80-x.
1.25x + 0.75(80-x) = 75
1.25x + 60 - 0.75x = 75
0.5 x = 15
x = 30
adult tickets = 30
child tickets = 80-30 = 50
