Angel has xx dimes and yy nickels. He has at most 13 coins worth no less than $0.95 combined. Solve this system of inequalities

ivanzaharov [21]

Answer:

a possible solution is (10,1)

Step-by-step explanation:

Here, we want to solve the given inequality and determine one possible solution

From the question, we have it that;

x + y ≤ 13

Mathematically, we have it that 1 dime is worth $0.1

A nickel is worth $0.05

0.1x + 0.05y ≥ 0.95

please check the attachment for the graph of both equations

The point of intersection represents the solution.

we have a point here as (10,1)
