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? Give me reasons, before answering the question
She had 8 records, received 12 and bought 30 for a total of 8 + 12 + 30 = 50 records. It takes 2 days to listen to 1 record and she has 50 records it will take her 2 * 50 = 100 days. So the final answer is 100.
