Let H be the amount of investments for high risk products, and
L be the amount for lowrisk products.
"with no more than $15,000 to invest "
H+L≤15000
"at least $2,000 is to be plaaced in the highrisk investment"
H≥2000
"amount invested at low risk should be at least three times the amount invested at high risk"
L≥3H
Draw a graph with H in the xaxis, and L in the yaxis (or vice versa).
Represent the above inequalities on the graph.
Shade the impossible regions. The unshaded region in the resulting graph represents the possible investment options.
