Rachel has 20 nickels, dimes, and quarters worth $3.70. if she has twice as many quarters as dimes, how many nickels does she ha
marta [7]

Answer: 2 nickels

Rachel has 20 coins composed of nickles, dimes and quarters amounting to $3.70. Her quarters are twice the number of her dimes, the number of nickels can be computed as follows:

If  X= the number of dimes  at .10 each

Then  2x= the number of quarters at .25 each and

20-(X-2X)= the number of nickels at .05 each

<span> <span><span> <span> The equation will be: X(.1)+2(X).25+(20-X-2X).10=3.70 </span> </span> <span> </span> <span> <span> .1X+2X(.25)+(20-X-2X).05=3.70 </span> </span> <span> <span> .1X+.5X+(20-3X).05=3.70 </span> </span> <span> <span> .6X+(1-.15X)=3.70 </span> </span> <span> <span> .6X+1-.15X=3.70 </span> </span> <span> <span> .45X=3.70-1 </span> </span> <span> <span> .45X=2.70 </span> </span> <span> <span> X=2.70/.45 </span> </span> <span> <span> X=6 number of dimes </span> </span> <span> <span> 2X=12 number of quarters </span> </span> <span> <span> 20-6-12=2 number of nickels </span> </span> </span></span>
