Fran baked 50 red macaroons and 40 green macarons. How many macaroons will remain if Fran ate 15 green macaroons and twice as many red macaroons as green macaroons?
After eating 15 green macaroons, the number is reduced to 40 green macaroons - 15 green macaroons = 25 green macaroons
If Fran ate 15 green macaroons, he also ate 2 red/green * 15 green macaroons = <<15*2=30>>30 red macaroons.
The total number of red macaroons remaining is 50 red macaroons - 30 red macaroons = <<50-30=20>>20 red macaroons
The total number of macaroons Fran has left are 20 macaroons + 25 macaroons = <<20+25=45>>45 macaroons
