Question

There were 744 tickets sold for a basketball game. The activity cardholder's tickets cost $1.75 and the non-cardholders tickets cost $2.25. The total amount of money collected was $1477.50. How many of each kind of ticket were sold?
Steve
if there were x cardholders, there were 744-x others. Now add up the money collected for each kind.

1.75x + 2.25(744-x) = 1477.50
1674.00 - 0.5x = 1477.50
x = 393
