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
Answer: They ate at the same pace.
Step-by-step explanation: assuming you want to know who ate more faster you can do 18 / 30 and 24 / 4 to find out who ate more in 10 seconds each.
18 / 3 = 6 and 24 / 4 = 6. So they ate at the same speed / pace.
