Answer:
9 Dimes & 6 Nickels
Step-by-step explanation:
9 × 10 = 90 cents
6 × 5 = 30 cents
90 + 30 = 120 which equals $1.20
The number of each of the coins that Nicole has are; 9 dimes and 6 nickels
Currency Conversion
Let number of nickels be x and number of dimes be y.
Thus; x + y = 15 - - - (1)
From currency conversions;
- 20 nickels make 1 dollar
- 10 dimes make 1 dollar
We are told that the total value of the coins is $1.2. Thus;
x/20 + y/10 = 1.2
Multiply through by 20 to get;
x + 2y = 24 - - - (2)
Subtract eq 1 from eq 2 to get;
2y - y = 24 - 15
y = 9
Thus; x = 15 - 9 = 6
Therefore, there are a total of 9 dimes and 6 nickels
