Natalie paid $14.99 to join an online music service. She purchases 9 songs each month at a cost of $0.99 per song. Natalie thinks that after 5 months, she will have spent around $60.00 total. Is Natalie's estimate reasonable?

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

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.
