Damien has 30 coins, all nickels and dimes. The total value of all these coins is $2.05. How many nickels does he have?

Damm [24]

Hi there!

nickels:19

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

1.Multiply two terms:

$10$ · $10=1.00$

Then there would be 20 nickels but 1+1=2 not 2.05.

2.Multiply the terms:

$11$ · $10=1.10$

$19$ · $5=0.95$

3.Combine the two terms:

$1.10+0.95=2.05$

Therefore, there would be 19 nickels...
