Hi there!
nickels:19
We know that there is only nickels and dimes in his coin collection..
1.Multiply two terms:
[tex]10[/tex]·[tex]10=1.00[/tex]
Then there would be 20 nickels but 1+1=2 not 2.05.
2.Multiply the terms:
[tex]11[/tex]·[tex]10=1.10[/tex]
[tex]19[/tex]·[tex]5=0.95[/tex]
3.Combine the two terms:
[tex]1.10+0.95=2.05[/tex]
Therefore, there would be 19 nickels...
