Question

Lincoln has X dimes and y quarters. He has no more than 24 coins worth at least $3.50 combined. Solve this system of equations graphically and determine one possible solution?

Answer 1

The system of equations solved graphically is (10, 11)

Solving the system of equations graphically

From the question, we have the following parameters that can be used in our computation:

No more than 24 coins

At least 3.50 combines

This means that

x + y ≤ 24

0.1x + 0.25y ≥ 3.50

Solving graphically, we have the solution to be in the shaded region

One of the possible solutions is (10, 11)
