Question

Aaliyah has x nickels and y pennies. She has a minimum of 20 coins worth no more than $0.40 combined. Solve this system of inequalities graphically and determine one possible solution. ​

Answer 1

Answer:

$(x,y) = (5,15)$

Step-by-step explanation:

Given

$Nickels = x$

$Pennies = y$

Minimum of 20 coins means:

$x + y \ge 20$

A nickel worth $0.05

A penny worth $0.01

So, the worth can be represented as:

$0.05x + 0.01y \le 0.40$

See attachment for graph

From the attachment, the solution is:

$(x,y) = (5,15)$
