Answer:
84 is the highest possible course average
Step-by-step explanation:
Total number of examinations = 5
Average = sum of scores in each examination/total number of examinations
Let the score for the last examination be x.
Average = (66+78+94+83+x)/5 = y
5y = 321+x
x = 5y -321
If y = 6, x = 5×6 -321 =-291.the student cannot score -291
If y = 80, x = 5×80 -321 =79.he can still score higher
If If y = 84, x = 5×84 -321 =99.This would be the highest possible course average after the last examination.
If y= 100
The average cannot be 100 as student cannot score 179(maximum score is 100)
X equals to 48

Answer:
The total monthly mortgage payment for the house is $975.63
Step-by-step explanation:
The principle amount is $175000
80% of 175000 is =
= $140000
20% of 175000 is =
= $35000
Emi formula is :

For 1st part:
p = 140000
r = 4.75/12/100=0.00395
n = 
Putting values in formula we get

= $729.508
For 2nd part:
p = 35000
r = 7.525/12/100=0.00627
n = 
Putting values in formula we get

= $245.301
Adding both the monthly payments:
dollars
This is closest to option A.
So, option A is the answer.
And for 30 years the mortgage payment will be =
