Question 81440
the sophomore class at south high school raised $800 from the sale of tickets to a dance. tickets sold for $1.50 in advance, and $2.00 at the door. if a total of 475 tickets were sold, the number of tickets sold at the door was
-------
Let # sold in advance = "x" ; Value of these is 1.5x dollars
# sold at the door = 475-x ; value of these is 2(475-x)= 950-2x dollars
------------
EQUATION:
value + value = 800 dollars
1.5x +950-2x = 800
-0.5x=-150
x=300 (# of tickets sold in advance)
475-x = 175 (# of tickets sold at the door)
