Given:
Principal = $1290
Rate of simple interest = 4%
Time = 9 months
To find:
The interest and total saving in the account altogether.
Solution:
The formula for simple interest is
...(i)
where, P is principal, r is rate of interest and t is time in years.
We know that,
Putting P=1290, r=4 and t=0.75 in (i), we get
So, the simple interest is $38.70.
Total savings is
Therefore, the total amount in the account altogether is $1328.70.

Below are the answers. Ontop are the questions.
You just need to see what letters and arrow matches the answer in the question.
Y - y1 = m(x - x1)
slope(m) = 2/5
(-4,-7)....x1 = -4 and y1 = -7....pay attention to ur signs
now we sub
y - (-7) = 2/5(x - (-4)...not done yet
y + 7 = 2/5(x + 4) <===
The slope of the line is -2/3.
This is found by using the equation y2 - y1/x2 - x1. Filling in for each factor, you would have 1-3/1+2 (since subtracting a negative makes it positive). This will give you a final answer of -2/3.
Here is a graph of the full equation of the line.
I hope this helps!
Answer:
A drink is 5 so two are 10...
And original cost-if saves 4 is 18
so 18-10=8
Popcorn is 8 dollars i think
