The number of half dollars coins are 5 and the number of the quarters dollars coins are 12.

<h3>What is the linear system?</h3>

A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.

You have a cup with 17 coins inside.

The total inside the cup is $5.50.

Let x be the number of half dollars and y be the number of the quarters dollars.

Then the equations will be

x + y = 17 ............1

0.5x + 0.25y = 5.5 ...........2

By solving equations 1 and 2, we have

x = 5 and y = 12
