Answer: 26 half dollars and 8 nickels

Step-by-step explanation:

Set nickel as X and half dollar as Y (or whatever you want)

then, write a system of equation to solve this problem

• x+y=34
• 0.05x+0.5y=13.4

Solve this equation by substituting x into (34-y)

then plug it into the equation of (0.05x+0.5y=13.4) which will become

0.05(34-y)+0.5y=13.4

 1.7-0.05y+0.5y=13.4

                0.45y=11.7

                        y=26

                        x=8
