Damm [24]

Hi there!

nickels:19

We know that there is only nickels and dimes in his coin collection..

<u><em>1.Multiply two terms:</em></u>

<u><em /></u>10<u><em>·</em></u>10=1.00<u><em /></u>

<u><em>Then there would be 20 nickels but 1+1=2 not 2.05.</em></u>

<u><em>2.Multiply the terms:</em></u>

<u><em /></u>11<u><em>·</em></u>10=1.10<u><em /></u>

<u><em /></u>19<u><em>·</em></u>5=0.95<u><em /></u>

<u><em>3.Combine the two terms:</em></u>

<u><em /></u>1.10+0.95=2.05<u><em /></u>

Therefore, there would be 19 nickels...

<u><em /></u>
