Yvette has up to $2000 to invest and has chosen to put her money into telecommunications and pharmaceuticals. The telecommunications investment is to be no more than 4 times the pharmaceuticals investment. Select ALL the equations or inequalities that could describe this situation. Let x represent the amount (in dollars) invested in telecommunications and y represent the amount (in dollars) invested in pharmaceuticals. (hint, there are 2)

• x + y >  2000

• x > 4y

• x + y <  2000

• x + y =  2000

• • 
    

    x <  4y
