On Wednesday, Carlo practiced for 50 + 5 = <<50+5=55>>55 minutes.
On Tuesday, he practiced for 55 - 10 = <<55-10=45>>45 minutes.
On Monday, he practiced for 45 x 2 = <<45*2=90>>90 minutes.
So, Carlo practiced for a total of 90 + 45 + 55 + 50 = <<90+45+55+50=240>>240 minutes from Monday to Thursday.
He needs to practice for a total of 60 x 5 = <<60*5=300>>300 minutes.
Therefore, he should practice for 300 - 240 = <<300-240=60>>60 minutes on Friday.
