Roberta started off with 8 vinyl records.  Her friends gave her 12 records for her birthday and she bought 30 more at a garage sale.  It takes her 2 days to listen to 1 record. How many days will it take her to listen to her record collection?
She had 8 records, received 12 and bought 30 for a total of 8+12+30 = <<8+12+30=50>>50 records
It takes 2 days to listen to 1 record and she has 50 records it will take her 2*50 = <<2*50=100>>100 days
