Question

Karla's doctor recommended her daily caffeine intake stay under 500 milligrams. Today, Karla has already had 430 milligrams of caffeine. Her favorite soda contains 35 milligrams. Which of the following inequalities could be used to solve for x, the number of sodas Karla can still have today?
35x + 430 < 500
35x < 500
35x - 430 < 500
35x < 930

Answer 1

This is really simple. So lets recall the problem. Karla already had 430 right. So any intake of caffeine with the 430 she took should be less than 500

Answer 2

In other words the answer is 35x + 430 < 500. Next question
