Question 1184655
<br>
x = # of nickels
11-x = # of dimes<br>
The total value is 70 cents:
{{{5x+10(11-x)=70}}}<br>
Solve using basic algebra; I leave that to you.<br>
You can solve the problem without formal algebra by examining different possible combinations of 11 dimes and nickels:<br>
11 nickels and 0 dimes: 55 cents
10 nickels and 1 dime: 60 cents
....<br>
It should be clear that only one combination of 11 dimes and nickels will have a total value of 70 cents.<br>
ANSWER: 1 combination of 11 dimes and nickels has a total value of 70 cents<br>
