How much do 20 cupcakes cost? ** 20 cupcakes cost 20 x $2 =$<<20*2=40>>40.
How much do 40 cookies cost? ** 40 cookies cost 40 x $1 = $<<40*1=40>>40.
How much money does Frances earn? ** So, Frances earns $40 + $40 = $<<40+40=80>>80 for selling cupcakes and cookies.
How much does Frances spend on trays? ** The cost of five trays is 5 x $4 = $<<5*4=20>>20.
How much money does Frances have left? ** Therefore, France will have $80 - $20 = $<<80-20=60>>60 left.
