Given that,
Ellen has $75 in her savings account she deposits 25 every week her father also deposit 35 into the account every time Ellen most salon
Suppose, her savings account balance can be shown with the following expression:

If Ellen saves for 8 weeks and most the salon 2 times, how much will she have in her account.
We know that,
When the numbers appear with variables it called coefficients.
When the numbers appear without variables it called constant.
Alphabets in an expression are called variables.
According to question,
25 and 35 are the coefficients and the number 75 appear without variables.
We need to calculate the balance in her account
Using expression
Put the value in the expression
Hence, She have 345$ in her account.
Answer:

Step-by-step explanation:
We know that the formula to find the middle point is:
We know that the middle point is:
And the end point is:
We wish to find the point
So we can write the following equation
(i)
and
(ii)
Now we clear from equation (i) and clear
from equation (ii)
For equation (i) we have:
For equation (ii) we have:
Then the initial point is:
The correct answer is the last option 3 +9i
