Answer:

[tex](x,y) = (5,15)[/tex]

Step-by-step explanation:

Given

[tex]Nickels = x[/tex]

[tex]Pennies = y[/tex]

Minimum of 20 coins means:

[tex]x + y \ge 20[/tex]

A nickel worth $0.05

A penny worth $0.01

So, the worth can be represented as:

[tex]0.05x + 0.01y \le 0.40[/tex]

See attachment for graph

From the attachment, the solution is:

[tex](x,y) = (5,15)[/tex]
