Solve.Yvette has up to $6000 to invest and has chosen to put her money into telecommunications and pharmaceuticals. The telecommunications investment is to be no more than 5 times the pharmaceuticals investment. Write a system of inequalities to describe the situation. Let x represent the amount (in dollars) invested in telecommunications and y represent the amount (in dollars) invested in pharmaceuticals.
A. x + y = 6000, x ? 5y, x ? 0, y ? 0 B. x + y ? 6000, x ? 5y, x ? 0, y ? 0 C. x + y = 6000, y ? 5x, x ? 0, y ? 0 D. x + y ? 6000, 5x ? y, x ? 0, y ? 0
