Pierce has 29 quarters and dimes with a total value of $4.25. how many of each coin does he have?

9 Quarters and 20 Dimes

Step-by-step explanation:

Let x = Quarters and y = dimes. You can write a system of equations with x+y=29 and 0.25x+0.10y = 4.25. Now you can solve using elimination: multiply x+y=29 by -0.10. You will end up with -0.10x-0.10y=-2.9 and 0.25x+0.10y=4.25.

Now add the 2 equations and you end up with 0.15x = 1.35. Divide both sides by 0.15 and you find x=9. Plug 9 in as x into the equation x+y=29 and you get 9+y=29. Subtract 9 from both sides and you find y=20. Make sure to check your work! Plug 9 and 20 into the first equation. 9+20=29. This is true.
