Answer:
The number of nickels is 15
The number of Dimes is 3
Step-by-step explanation:
Let the number of dimes Christine has be d
The number of nickels with christine be n
Then the number of Nickels Christine has will be
n = 5d ----------------------------------(1)
Now The total value of both dimes and nickels is = $1.05
This can be represented as
5n +10d = 105 (in cents)
From eq(1)
5(5d) + 10d = 105
25d+10d = 105
35d = 105

d = 3----------------------------------(2)
Substituting (2) in (1), we get
n = 5(3)
n = 15
