Posted by mario on Wednesday, March 28, 2007 at 10:59pm.

drama club sold adult tickets for $8 and kid tickets for $5. for the final performance a total of 226 tickets were sold for a total of $1670. how many adult tickets were sold for the performance?

X = # of adult tickets
Y = # of kid tickets

X + Y = 226
8X + 5Y = 1670

Solve those two equations in two unknowns. One way would be to use substitution. (Insert 226 - X in place of Y in the second equation).
