Answer:
Number of nickels: 14
Number of dimes: 31
Total money: $3.80
Step-by-step explanation:
Let number of nickels be x
Number of dimes is 2x+3
Total coins = 45
So add the number of nickels and dimes and it equals 45
x+2x+3=45
3x=45-3=42
x=42/3=14 nickels
Substitute the value of x=14 in 2x+3 to find number of dimes
2(14)+3=28+3=31 dimes
Total money is 14 nickels + 31 dimes
Nickels = 0.05 and dimes is 0.10
14(0.05)+31(0.10)=0.7+3.1=3.8
