<PRE><B>Question 301631</B>
There are 1000 spaces. Regular Parking is $5. Prefered parking is $10. They sold out $5750. How many of each type of parking are available?

let regular parking spaces be x

prefered will be 1000-x

5x+10(1000-x)= 5750

5x+10000 - 10x= 5750

-5x=-4250

x= -4250/-5

x=850 regular spaces

balance will be 150 which is prefered space



$12 adult tickets were sold.
$7 student tickets were sold.
A total of 122 tickets were sold adding up to $1,099 total. How many student tickets were sold?

let student tickests sold be x

adult tickets sold will be 122-x

7x+12(122-x)=1099

7x+1464-12x=1099

-5x=-365

x=365/5
x= 73 tickets student tickets
