Macy bought some records. She spent a total of $45 after a discount of $11 off of her total purchase. Each record cost $8. How many records did she buy?

Select an equation that could be used to answer the question above. Let r represent the number of records.


8r - 11 = 45

45r - 11 = 8

11r + 8 = 45

8r + 45 = 11
