Answer: You can send or receive a maximum of 21 text messages per month.
First, you need to take out the number the phone bill costs (24.99)
29 - 24.99 = 4.01
Then, you need to find out how many 0.19 fit into 4.01.
21 * 0.19 = 3.99. Any more than that and it would go over.
find the current mean(average), then add 10, last divide by 1.3
For average sized artwork (about 11x14" to 30x20"), the common mat width is 2". If you artwork is smaller, you might consider a 1.75 or 1.5" mat.
