Baked goods

The basketball team sells brownies for $1.50 and rice krispies for $1.00. They sell 309 goodies in all. How much of each did they sell? I'm confused on how to make the equations.

With the information that you have provided, there is no single definitive answer.  Did you omit the total income from all sales?

It says they wanted to make back $350 that they spent on posters. Would that count as the total income?

Yep, now let b = # of pkgs of brownies sold & k = # of krispie pkgs sold.
 
$350 = 1.5b + 1k    ⇐ equation says total income, coming from b pkgs @ 1.5 $ each + k pkgs @ $1
b+k = 309.             ⇐ equation says  total # of packages sold
 
Now you have a system of 2 unknowns & 2 equations & I know you can sold that.
