Question 135055
Let's deal in pennies, ok
Let x=number of nickels;  value of the nickels=5x
Then x+5=number of dimes;  value of dimes=10(x+5)=10x+50
And 2x=number of quarters; value of quarters=25*2x=50x

Now we are told that the total value is 440, so:

5x+10x+50+50x=440  subtract 50 from each side

5x+10x+50x+50-50=440-50  collect like terms
65x=390  divide both sides by 65

x=6-------------------------number of nickels
x+5=6+5=11------------------------number of dimes
2x=2*6=12-------------------------number of quarters

CK
6*5+11*10+12*25=440
30+110+300=440
440=440
