Question 52060
The number of nickles is: N
The number of dimes is 2 less than twice the nickles: 2N-2
(The number of nickles)+(the number of dimes)=52  Therefore:
N+2N-2=52
3N-2=52
3N-2+2=52+2
3N=54
3N/3=54/3
N=18
The number of nickles "N" is 18
The number of dimes is 2N-2
Substitute 18 in for N and you have:  2(18)-2=34
Nickles are worth 5 cents, so you have 5(18)=90 cents in nickels
Dimes are worth 10 cents, so you have 10(34)=340 cents in dimes
90+340=430 cents all together or $4.30
