The tens column is the one directly to the right of the decimal, so you need to get rid of the seven. Since the 7 is closer to ten than it is to zero (it's bigger than 5), you will round up. When you round up, you add 1 to the number on the left, the 9. So it will become 10, or 1.0

Answer:
50 nickels, 20 quarters.
Step-by-step explanation:
System of equations (q = # of quarters, n = # of nickels):
<em>q + n = 70, 0.25q + 0.05n = 7.50</em>
the first equation can be changed to q = 70 - n, so we are able to <em>substitute q with 70 - n</em>.
So, it will look like <em>0.25*70 - 0.25n + 0.05n = 7.50</em>. This can be simplified to <em>0.2n = 10</em>, which means that n = 50.
Knowing that we can solve <em>q + 50 = 70</em>, which means that q = 20.
