Faye's mother gave her 2 x $20 = $<<2*20=40>>40.
So, Faye had a total of $20 + $40 = $<<20+40=60>>60.
Ten cupcakes cost 10 x $1.50 = $<<10*1.5=15>>15.
Five boxes of cookies cost 5 x $3 = $<<5*3=15>>15.
Thus, Faye spent $15 + $15 = $<<15+15=30>>30.
Therefore, Faye has $60 - $30 = $<<60-30=30>>30 left.
