Answer:
Equation of the line that models the amount of money y in her account x years from now.
Step-by-step explanation:
Given: Christie has $200 in her bank account. She deposits $20 in a month into her account.
as per the given statement:
In 1 month she deposits $ 20
then,
in 1 years(i.e 12 months) she deposits =
Let y be the amount of money and x be the number of years.
then,
the equation of line models the amount of money y in her account x years from now is;
First, , and if we multiply
by
we get
Subtracting this from the numerator gives a remainder of
Next, , and if we multiply
by
we have
and subtracting this from the previous remainder, we end up with a new remainder of
Next, , and if we multiply
by
we get
Subtracting from the previous remainder, we get a new remainder of
which contains no more factors of , so we're done.
So,
