John makes 6 dozen cookies for a bake sale.  He sells each cookie for $1.5 and each cookie costs $0.25 to make.  He splits the profit between two charities evenly.  How much does each charity get?
He makes 6*12=<T>multiply(6, 12)=72 cookies
Each cookie makes a profit of $1.5 - $0.25=$<T>subtract(1.5, 0.25)=1.25
So he makes a profit of 72*$1.25=$<T>multiply(72, 1.25)=90.0
That means each charity gets $90/2=$<T>divide(90, 2)=45.0
