Elena is designing a paint can with thickness t millimeters and height h centimeters. She
calculates that the thickness of the can in milimeters must be at least 0.1 times the height of the
can in centimeters in order to withstand pressure. Due to cost constraints, the cost of material
used, (0.2+t+ 0.5h) cents, must be at most 12.2 cents. Which of the following systems of
inequalities best models the relationship between height and thickness described above?
