Question

2. The number of nickels that Christine has is

Answer 1

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

$d = \frac{105}{35}$

d = 3----------------------------------(2)

Substituting (2) in (1), we get

n = 5(3)

n = 15
