Answer:
Number of essay questions are 9.
Step-by-step explanation:
Let the number of multiple choice questions = x and the number of essay questions = y.
As, the total number of question are 26. We get,
Also, the multiple choice and the essay questions worth 3 and 8 points each.
Since, the total number of points of the test are 123.
So, we have,
So, the system of equations is,
x+y=26 ...........................(1)
3x+8y=123 ............................(2)
Multiply (1) by 3 and subtracting by (2), we get,
5y = 45 i.e. y = 9
So, x+y=26 implies x = 26 - y i.e. x = 26 - 9 i.e x = 17
Thus, the number of multiple choice questions and essay questions are 17 and 9 respectively.
Answer:
Option D is correct.
Step-by-step explanation
Principal = $9250
rate of interest = 7% or 0.07

Amount after t years =
where P = principal
r = rate % in decimals
n= number of times in a year
t = times ( in years)
plugging the values in the formula
Amount =
=
=
= 9250(1.418733588)
=$13123.29
