Jasmine is on a cell phone plan where she pays $20 a month plus 10% for text message she does not want to spend more than $40 on her cell phone bill right and saw the i n e q u a l i t y that will tell her how many texts message can she send

Let x be the number of text messages Jasmine can send.

The cost of the text messages would be 10/100 * x = 0.1x.
Jasmine's total cell phone bill is $20 + $0.1x.
To make sure she does not spend more than $40, the inequality is:
20 + 0.1x ≤ 40.
