Let Craig bough x calendars.

The cost of 3 calendars is $27.

Hence, the cost of 1 calendar is 27/3 = $9

Now, it has been given that she spent another $18 for more calendars. And we have calculated that cost of 1 calendar is $9.

Hence, in $18 she could buy 2 more calendars.

Therefore, the number of calendars she bought is given by

3 + 2

= 5

She bought 5 calendars
