question: Suzanne sold 80 cookies for $1 each and 60 cupcakes for $4 each. She gave her two sisters $10 each for helping her. How much money does she have left from her earnings?
answer: Suzzane's revenue from the cookies is 80 x $1 = $<<80*1=80>>80.
  Her revenue from the cupcakes is 60 x $4 = $<<60*4=240>>240.
  Her total revenue for the cupcakes and cookies is $240 + $80 = $<<240+80=320>>320.
  She gave a total of 10 x 2 = $<<10*2=20>>20 to her sisters for helping her,
  So, Suzzane has $32 - $20 = $300 left.
  #### 300
