Answer: 14 nickels and 18 quarters.
Step-by-step explanation:
Let x = Number of nickels , y = Number of quarters
As per given , we have
x+ y= 32 (i)
0.05x+0.25y= 5.20 (ii)
Multiply (ii) by 4 , we get
0.2x+y = 20.8 (iii)
Subtract (iii) from (i) , we get
0.8x = 11.2
[tex]\Rightarrow\ x=\dfrac{11.2}{0.8}\\\\\Rightarrow\ x = 14[/tex]
Put value of x in (i) , we get
y =32-14 = 18
Hence, we have 14 nickels and 18 quarters.
