Let the number of nickels be = n
Let the number of dimes be = d
Let the number of quarter be = q
Total money William has = $12.80
As given, there are 3 times as many quarters as nickels
And 20 more dimes than nickels
As total money is $12.80
Putting the values of 'q' and 'd' to find 'n'
Hence the number of nickels are = 12
If you want to also find dime and quarter, then
X(2x²-9x+10)=x(2x-5)(x-2)=0.
x=0 is one solution.
2x-5=0 and x-2=0 give us the solutions x=5/2 and x=2.
So x=0, 2 or 5/2.
We find the difference of the two numbers by subtracting the two numbers given above. It is calculated as follows:
Difference = 20000 - 4632 = 15368
Therefore, the difference between <span>4,632 and 20,000 is 15368.
Hope this answers the question. Have a nice day.</span>
