a. Her monthly average would have decreased by $19.57.

Step-by-step explanation:

To find out how not working on November would affect the average of Katie's tips, we first need to find the average of her working June until October only.

Average = 133.45 + 235.31 +239.45 + 258.87 + 298.45/5

Average = 1165.53 / 5

Average = $233.10

Now let's find out what her average is with the month of November.

Average = Average = 133.45 + 235.31 +239.45 + 258.87 + 298.45 + 115.67/6

Average = 1281.2 / 6

Average = 213.53

So now we can compare both averages.

233.10 - 213.53 = $19.57

We know that her average will decrease because 213.53 < 233.10.

Her average will decrease by $19.57.

Correct answer is B.) Her monthly average would have increased by $19.57.
