Question 233390
<font face="Garamond" size="+2">


Let *[tex \Large x] represent the number of posters.  Let *[tex \Large y] represent the number of t-shirts.  Then the amount of money collected for posters would be *[tex \Large 20x] dollars and the amount of money collected for t-shirts would be *[tex \Large 25y] dollars.


Using the data given:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ x\ +\ y\ =\ 1000]


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ 20x\ +\ 25y\ =\ 22000]


Solve the system.  The values of *[tex \Large x] and *[tex \Large y] are the numbers of posters and t-shirts sold.
