Answer: There are 7 nickles, 21 dimes and 16 quarters.
Step-by-step explanation:
Since we have given that
Number of coins = 44
Let the number of nickels be 'x'.
Let the number of dimes be '3x'.
Let the number of quarters be
![44-(x+3x)\\\\=44-4x](https://tex.z-dn.net/?f=44-%28x%2B3x%29%5C%5C%5C%5C%3D44-4x)
According to question, we get
![0.05x+0.10(3x)+0.25(44-4x)=6.45\\\\0.05x+0.3x+11-x=6.45\\\\-0.65x=6.45-11\\\\-0.65x=-4.55\\\\x=\dfrac{4.55}{0.65}\\\\x=7](https://tex.z-dn.net/?f=0.05x%2B0.10%283x%29%2B0.25%2844-4x%29%3D6.45%5C%5C%5C%5C0.05x%2B0.3x%2B11-x%3D6.45%5C%5C%5C%5C-0.65x%3D6.45-11%5C%5C%5C%5C-0.65x%3D-4.55%5C%5C%5C%5Cx%3D%5Cdfrac%7B4.55%7D%7B0.65%7D%5C%5C%5C%5Cx%3D7)
So, there are 7 nickles,
3x =![3\times 7=21](https://tex.z-dn.net/?f=3%5Ctimes%207%3D21)
![44-4x=44-4\times 7=44-28=16](https://tex.z-dn.net/?f=44-4x%3D44-4%5Ctimes%207%3D44-28%3D16)
Hence, there are 7 nickles, 21 dimes and 16 quarters.
