Multiple Choice

Use Mathematical Models Involving Linear Inequalities
-A person with no more than $1000 to invest plans to place the money in two investments, telecommunications and pharmaceuticals. The telecommunications investment is to be no more than 3 times the pharmaceuticals investment. Write a system of inequalities to describe the situation. Let x = amount to be invested in telecommunications and y = amount to be invested in pharmaceuticals.

• A) \(x + y \leq 1000\)
• \(x \leq 3 y\)
• \(x \geq 0\)
• \(y \geq 0\)
• B) \(x + y = 1000\)
• \(x \leq 3 y\)
• \(x \geq 0\)
• \(\mathrm { y } \geq 0\)
• C) \(x + y = 1000\)
• \(y \geq 3 x\)
• \(x \geq 0\)
• \(y \geq 0\)
• D) \(x + y \leq 1000\)
• \(3 x \leq y\)
• \(x \geq 0\)
• \(y \geq 0\)
