Step-by-step explanation:

Greta mails 4 postcards on Monday, Wednesday, and Friday.

So she mails a total of 12 postcards on Monday, Wednesday, and Friday.

She mails 5 postcards on Tuesday and Thursday. This means that she mails a total of 10 postcards on Tuesday and Thursday.

She mails no postcards on

Saturday or Sunday. This means she mails a total of 0 postcards on Saturday and Sunday.

There are a total of 7 days in a week.

She mails a total of 22 postcards.

If she does this for the entire 12 weeks that she is studying abroad,

She would be sending 12 * 22 = 264 mails.

She believes that she will mail over 200 so 220 and 240 applies.
