Answer:
130 dimes
Step-by-step explanation:
A nickel is worth 5 cents = 0.05n
A dime is worth 10 cents = 0.10d
Taliyah has 174 coins in her collection of dimes and nickels.
n + d = 174
n = 174 - d
The total value of the collection is $15.20.
0.05n + 0.10d = $15.20
We substitute 174 - d for n
Hence:
0.05(174 - d) + 0.10d = 15.20
8.7 - 0.05d + 0.10d = 15.20
- 0.05d + 0.10d = 15.20 - 8.7
0.05d = 6.5
d = 65/0.05
d = 130 dimes
The number of dimes she has in her collection is 130 dimes
