Final answer:
To solve the system of inequalities, we graph the constraints and find the feasible region.
Step-by-step explanation:
To solve this system of inequalities graphically, we need to create a graph and plot the constraints. Let's start by defining our variables:
x = number of dimes
y = number of nickels
We are given the following information:
1) Mayerlin has xx dimes and yy nickels. This gives us the first constraint: x ≥ 0 and y ≥ 0.
2) Mayerlin has no more than 20 coins. So the second constraint is: x + y ≤ 20.
3) Mayerlin's coins are worth no less than $1.30 combined. Each dime is worth $0.10 and each nickel is worth $0.05. Therefore, the third constraint is: 0.10x + 0.05y ≥ 1.30.
