Question

At a college function, a total of 180 tickets were sold. The tickets were priced at $5, $10, and $15, and the money collected that day was $1,900. The sum of the numbers of $5 and $15 tickets sold was twice the
number of $10 tickets sold. Find the number of each type of ticket sold for the college function.

Answer 1

If the quantity of tickets is x,y,x for t5,10,15 dollar tickets, respectively, then we have

x+y+z = 180
5x+10y+15z = 1900
x+z = 2y

(x,y,z) = (50,60,70)
