Answer:
Yes,Natalie's estimate is reasonable
Step-by-step explanation:
If Natalie bought 9 songs every month for 5 months for $0.99 each that would be $44.55 in total for the 5 months.
Because 9 × $0.99 = $8.91 for 9 songs in one month, so to find how much she would have spent on songs in 5 months we would multiply $8.91 × 5 and that would be $44.55.
And also how much she paid to join the class $14.99 would the total of how much she spent to $59.54
